1 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
3 * configure.in, xconfig, tconfig: Makefile fragments for various
4 hosts and targets now come from gdb/config/mh-* and
5 gdb/config/mt-*. This is for consistency with other config setups.
7 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
8 * rs6k-opcode.def: Delete.
10 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
12 * dwarfread.c: Recognize obsolete form of AT_element_list
13 attribute still used by at least one AT&T compiler, and possibly
16 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
18 * dwarfread.c (enum_type, struct_type): Ignore names invented by
19 helpful compilers for anonymous structs, unions, and enums.
21 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
22 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
23 can coexist in the same executable without collision.
25 * symtab.h: Add declaration for lookup_template_type() to kill
26 compiler warnings about conversions from int to pointer.
28 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
30 * procfs.c: Move inclusion of defs.h to before param.h, as in
31 all the other source files that include both. This is required
32 to supply some typedefs that are used in files included by param.h.
34 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
35 skipping function prologues, ala the other cpu families (i386,
36 mips, m88k, etc). Add the ability to skip movm and fmovm
37 instructions in the prologues. Still needs support for profile
38 (-p compiled) prologue sequences (FIXME).
40 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
41 m68k prologue skipping function by default.
43 * tm-altos.h, tm-isi.h: Continue to use the old definition of
46 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
48 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
49 * blockframe.c: Remove tdesc-related code. Default
51 * infrun.c: Remove tdesc-related code.
52 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
53 of defaultable things.
54 * tm-m88k.h: New file, common to all Moto 88k target configs.
55 Derived from tm-delta88.h.
56 * tm-delta88.h: Use it.
57 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
58 * xm-delta88.h: Use it.
59 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
61 * coffread.c: Remove tdesc stuff.
62 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
63 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
65 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
67 * source.c (open_source_file): If openp fails, try again
68 using just the base (non-directory) part of the filename.
69 This solves various annoying problems, such as when the
70 source was compiled with an absolute pathname - and the
71 source files have moved. Or if the source was compiled
72 using a relative pathname, it can be more convenient
73 to just specific the source directory to the dir command.
75 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
77 * cplus-dem.c (munge_function_name): Add missing third arg to
78 instance of call to do_type().
80 * dwarfread.c: Changes to match new dwarf.h. Remove
81 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
84 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
86 * symtab.h (struct type): Moved C++-specific fields into new type
87 `struct cplus_struct_type'. Now takes 10% less memory. Many
89 * symtab.c (init_type): Don't set fields belonging to
90 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
91 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
93 (read_struct_type): Ditto. Also, add comments about how we can
94 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
95 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
97 (read_struct_type): Ditto.
98 * dwarfread.c (struct_type): Ditto.
100 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
101 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
102 (lookup_reference_type): Ditto.
104 * cplus-dem.c: Many changes made to handle decoding of

111 * mipsread.c (parse_partial_symbols): patch to keep DEC C
112 compiler from making gdb bomb out. Thanks to Ed Santiago!
114 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
116 * symfile.c: Add function compact_misc_function_vector() to
117 remove duplicate misc function vector entries. See comments
118 in source for why this is necessary/desirable.
120 * dwarfread.c: Add misc function type parameter to internal
121 record_misc_function(). Remove calls to init_misc_bunches()
122 and condense_misc_bunches(), these are now done in elfread.c.
124 * elfread.c: Add support for reading bfd canonical symbol tables
125 and generating misc function vector entries for global and
126 absolute symbols. Do calls to init_misc_bunches() and
127 condense_misc_bunches() where they will enclose all calls to
128 record_misc_function(), including those in dwarfread.c.
130 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
132 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
133 (roffable documentation).
134 * doc/gdb.texinfo: embedded hints (as comments) for better
135 texi2roff conversion.
137 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

151 Motorola 88000 port without tears, I mean without tdescs.
153 * m88k-tdep.c: Blow away all tdesc stuff.
154 Provide functions for all the frame-related macros in
155 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
156 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
157 from i960-tdep.c and adapt to the function prologues on the 88k.
158 (read_next_frame_reg): Borrow from mips-tdep.c.
159 FIXME: frame_locals_address should go away.
161 * tm-delta88.h: Dump all the tdesc stuff.
162 Macros for all frame-related stuff call fns of same name.
163 Remove duplicated definitions. FP_REGNUM becomes same as
166 * xm-88k.h: Eliminate lots of library dependencies, now handled
167 in libiberty. Eliminate KDB nonsupport.
169 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
172 * stack.c (frame_info): Mark frameless functions.
173 Print locals address (FIXME, remove if same).
174 * blockframe.c: Comment changes, FIXME after.
175 * coffread.c: Even without TDESC, need to zap "@" symbols.
176 Don't register for wierd format names; change the names in BFD.
178 * alloca.c, language.c, tdesc.c: Lint.
179 * tdesc.c, tdesc-lib: FIXME: remove these.
181 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
183 * Makefile.in: Add tdesc library support. Fixups to lint,
186 Tue Nov 12 13:43:26 1991 Per Bothner (bothner at cygnus.com)
188 * symtab.c (decode_line_1): Remove spurious call to operator_chars.
190 Allow setting breakpoints on C++ destructors.
191 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
192 since it lies. Rely on callers to catch missing destructors.
193 * symtab.c (decode_line_1): For example (see above), here.
194 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
195 flags since they are no longer used.
197 Fixes to support C++ methods with functional parameters.
198 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
199 types in a function type.
200 * eval.c (parse_and_eval_type), value.h: New function,
201 parse_and_eval_type, is based on old code from check_stub_method.
202 But don't actually evaluate the cast, since that calls
203 value_cast(), whcih may fail. Just extract the type
204 from the parsed expression.
205 * values.c (check_stub_method): While looping through the
206 arguments, adjust depth *after* parameter has been handled.
207 Replace call and setup of parse_and_eval with new function
210 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
212 * utils.c, rem-multi.shar: Remove fixed arg count version of
215 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
216 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
217 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
218 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
219 Change all instances of use of fixed args concat() to variable
220 args concat() now located in libiberty.
222 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
224 * Makefile.in: Add xcoffread.c, xcoffexec.c.
225 * xcoffread.c: New file for handling AIX mangled-coff files.
226 * xconfig/rs6000, tconfig/rs6000: New files.
227 * buildsym.c: Add hooks for xcoffread.c.
228 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
229 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
230 * xcoffexec.c: New file for handling AIX shared libraries.
232 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
234 * core.c: Minor rewording of message to user containing name of
235 (and possibly arguments to) the program that generated a core
238 * elfread.c: Remove the register_addr() stub now that it is no
241 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
242 fetch_core_registers() function for core file support.
244 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
246 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
247 to do_cleanups() which resulted from a previous change.
249 * elfread.c: Re-enable compilation of register_addr() stub
250 whenever it is not supplied by coredep.c
252 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
254 Add tracking of object files (that contain symbols) to gdb.
255 This includes a "struct objfile" that owns symtabs and psymtabs
256 that were read in from that binary file.
258 * symfile.h: Add struct objfile. Add pointer to the objfile
259 into the struct sym_fns.
260 Replace global `symfile' and `symfile_mtime' with
261 `symfile_objfile'. Add global object_files chain.
263 * symfile.c: Move param.h above symtab.h.
264 (sort_misc_function_vector): Add.
265 (syms_from_objfile): Was syms_from_bfd.
266 (symfile_open): Now returns objfile.
267 (allocate_objfile): New.
268 (free_objfile): New, replacing free_all_.*symtabs.
269 (symfile_init): Takes objfile arg, puts it in sym_fns result.

271 (allocate_symtab): Takes objfile as new parameter, chains them.
272 Handle INIT_EXTRA_SYMTAB_INFO.

275 * dbxread.c: Make more errors into complaints.
276 (push_subfile, pop_subfile): Move to buildsym.c.
277 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
278 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
279 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
280 Pass objfile. Change callers.
281 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
282 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
283 (end_psymtab): Blow away psymtab if empty.

288 * buildsym.c (end_symtab): Pass objfile.
289 (dbx_lookup_type): Handle null typevector.
290 (dbx_alloc_type): Check file number, not sym number, for -1.
291 (find_symbol_in_list): Add for xcoffread.
292 (start_symtab): Default typevector is empty. Keep reusing same
294 (end_symtab): Take objfile argument and pass it to
295 allocate_symtab. Don't make a symtab if no blocks or symbols.
296 Handle empty typevector.
297 (push_context): New function for context stack nesting.
298 (read_type): Mark FIXME where we need to reintroduce type smashing.
300 * buildsym.h (pop_context): Macro, paired with push_context.
301 (subfile_stack): Move here from dbxread.c.
303 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
304 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
306 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
307 new_psymtab, new_symtab): Take and use objfile arg.
309 * dwarfread.c (scan_compilation_units, start_psymtab,
310 process_dies, end_symtab, dwarf_build_psymtabs,
311 read_lexical_block_scope, read_func_scope, read_file_scope): Take
312 and use objfile argument.
313 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
314 descriptor. Use BFD internal functions instead.
315 (end_symtab): Call global allocate_symtab.
317 * elfread.c, target.c: Minor changes to accommodate objfiles.
318 * symtab.h: partial_symbol_table has no symfile_name member now.
319 (fn_fieldlists voffset): avoid non-int bitfield.
320 (struct symtab): Add objfile * and objfile_chain * of symtabs.
321 (struct partial_symtab): Add objfile * and objfile_chain * of
322 psymtabs. Remove symfile_name.
324 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
325 (printsyms_command): Rename from print_symtabs. Add selective
326 listing if 2nd argument given. Print objfile info.
327 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
328 (printobjfiles_command): New; prints objfiles lists, and checks
329 for consistency of symtab, psymtab, and objfile lists.
331 * symfile.h, symfile.c, symtab.h: Lint
333 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
335 * command.c: Include param.h.
336 * defs.h (warning_setup, warning): Declare.
337 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
338 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
339 * language.c, printcmd.c (print_scalar_formatted), signame.c,
342 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
344 * Makefile.in: link with libiberty after libreadline, since
345 readline might want something in libiberty.
346 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
347 struct for BCS 88k machines.
348 * xm-m88k.h: don't define USIZE if already defined.
349 * configure.in: Added delta88 target.
351 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
353 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
355 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
356 READ_MIPS_FORMAT, which have been unused since BFD. Still
357 remaining is COFF_NO_LONG_FILE_NAMES.
358 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
359 function calling code moved to m68k-tdep.c.
361 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
363 * coffread.c: Eliminate c_nsyms in favor of c_naux.
364 Complain if no auxents on .bf and .ef FCN symbols, and assume
365 lots of line numbers.
366 (init_linenos, enter_linenos): Use a sentinel at the end of the
367 read-in linenos, to make for a fast, safe loop-end test.
369 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
371 * coffread.c (read_coff_symtab): coffread used to rely on the
372 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
373 function. Two of the formats I'm using (29k and 88k) don't seem to
374 set it. Ths patch to fcn_last_line and (enter_linenos) is an
375 attempt to use the actual size of the linno table in the file to set
376 the number of linenos to process.
378 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
380 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
381 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
382 are created in place, so the mv fails, then the make continues.
384 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
386 Add C++ as a separate language.
387 * defs.h (enum language): Add language_cplus.
388 * dwarfread.c (end_symtab): Support language_cplus.
389 * c-exp.y: Add new struct language_defn cplus_language_defn.
390 Don't set c to be the default language (see main.c).
391 * c-exp.y (yylex): Only look for field of this if
392 language is C++. (First difference from C!)
393 * language.c: Add case branches for C++ (currently, all
394 the same as C). Also, add c++ to "usage" note for "set lang".
395 * valprint.c (typedef_print). Add case branches for C++.
396 * main.c (main): New way to set initial language: Look at
397 file extension of psymtab containing main(). (Same as we
398 do for symtabs, but avoid loading the symtab yet.)
399 * symtab.c: New routine find_main_psymtab(), used by main()
400 to set initial language.
401 * symfile.c (allocate_symtab): Move code for mapping file
402 extensions-> languages to new deduce_language_from_filename().
404 Fix a C++ problem when looking for methods in super-classes.
405 There was confusion between base and derived types.
406 * valops.c (value_fn_field): Change function interface.
407 * values.c: Use new value_fn_field interface.
409 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
411 * infrun.c: Fixed typo in comment.
412 * utils.c: All the v*fprintf emulation is now in libiberty,
413 so we can get rid of some junk.
414 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
415 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
416 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
417 type operands, as used by branch instructions.
418 * gmalloc.c: Fix prototype of memcpy.
419 * elfread.c: Comment out register_addr, since it conflicts
420 with the one in coredep.c.
421 * buildsym.h: Remove extern declarations of two functions
422 that are really static in buildsym.c.
423 * tm-mips.h: Add symbolic names for more registers.
424 * mips-xdep.c (store_inferior_registers): Use new register names.
425 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
426 only used for core files, not ptrace. Therefore,
427 the KERNEL_U_ADDR hack is no longer needed.
428 The mapping to ptrace number is now in in mips-xdep.c.
429 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
430 mapping from the old REGISTER_U_ADDR), and use it
431 in {fetch,store}_inferior_registers.
432 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
433 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
434 Save/restore FP regs correctly (?).
435 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
436 (these had been previously moved to buildsym.c).
437 Hence, define_symbol becomes extern instead of static.
438 * buildsym.c (read_struct_type): Comment out bogus handling
439 of C++ operator methods. Minor hacking of reading of class
440 contexts. Make define_symbol non-static, so dbxread.c can call it.
442 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
444 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
445 filename with error messages.
446 * stack.c (frame_select_command): Rename to select_frame_command
447 to avoid "fr" and "fra" having nonunique completions.
448 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
449 (symfile_init): Print file format name when unable to handle it.
450 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
451 * symmisc.c (free_symtab): Only free linetable if nonzero.
452 * symtab.h: Remove obsolete BLOCKLIST macros.
454 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
456 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
457 that stop_step is 1 at bottom of main loop. I don't know why this
458 needs to be done, but it helps me sleep better at night.
460 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
462 * main.c (initialize_history): Read history after reading all
465 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
467 * buildsym.c: Break out initial malloc sizes.
468 (record_line): Record directly in a subfile. Alloc on demand.
469 (compare_line_numbers): Add from xcoffread.c.
470 (end_symtab): New params say whether to sort pendings and
471 linetable. Patch block stabs if defined. Shrink linetable before
472 allocating the symtab.
473 * buildsym.h: Delete line_vector* and prev_line_number. Add
474 global_stabs and file_stabs for xcoffread.
475 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
476 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
477 * symmisc.c, symtab.c: Cope with null LINETABLEs.
479 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
480 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
481 tm-sparc.h: Accept fromleaf parameter.
482 * c-exp.y (yyerror): Pass error message if given.
483 * configure.in: Add rs6000 host and target.
484 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
485 * symfile.h (entry_point): Add.
487 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
489 * buildsym.c: New file. Breaks out symbol-table-building routines
490 from dbxread.c, so they can be shared with xcoffread.c.
491 * buildsym.h: New file. Declarations for buildsym.c users.
492 * dbxread.c: Remove large chunks into buildsym.c.
493 * Makefile.in: Add buildsym.c and buildsym.h.
495 * symfile.c (syms_from_bfd): New routine.
496 (add_symbol_file): Call it to do the real work.
497 (syms_from_bfd): Initialize entry_point before calling symfile_init.
498 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
499 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
501 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
503 * cplus-dem.c (cplus-demangle): added support for templates, static
504 data, and the new (correct) mangling for destructors.
506 * dwarfread.c: (dwarfwarn): created a varargs version of
507 dwarfwarn, for non __STDC__ compilers.
509 * c-exp.y: (yylex): added match for "template" token.
510 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
511 specification of template types.
513 * symtab.c: (lookup_template_type): new function for finding
514 templates in symbol table.
515 (type_name_no_tag): changed to explicitly check for s/u/e at the
516 beginning of the symbol - if it is a template, none of these will
517 be there (but the name will still contain spaces.)
519 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
521 Various fixes to improve g++ debugging.
522 * symtab.h: Add is_const and is_volatile flags for each method.
523 These are bit fields - take their space from voffset,
524 which shrinks to 30 bits. Since voffset is now a bitfield,
525 make it unsigned for portability. This changes its interpretation
526 slightly: Static methods now have voffset 1 instead of -1,
527 and virtual offsets start at 2, not 1.
528 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
529 since it now returns an entire magled method name, not just
530 the type part. This avoids some duplication.
531 It also allows us to correctly mangle const and volatile
532 methods (using the new is_const and is_volatile bit fields
534 * valprint.c (type_print_base), values.c (check_stub_method):
535 Simplify by using new gdb_mangle_name.
536 * values.c (value_headof): Fix to correctly handle single
537 inheritance (actually two fixes, either of which suffices).
538 * dbxread.c (read_struct_type): Handle const and volatile
540 * dbxread.c (read_struct_type): Yet one more place where
541 we must handle '\\' continuations.
542 * valprint.c (vtbl_ptr_name): Add final '\0'.
544 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
546 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
547 short return values for sparc and 68k. Patch from Paul Eggert.
549 * coffread.c, coredep.c, i386-xdep.c: install patches for
550 SysV/386 3.2 from Mauro DePalma.
552 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
554 * core.c (core_file_info), exec.c (exec_file_info): Print file
555 type. Use printf_filtered.
557 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
559 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
561 * dwarfread.c: Add casts to remove compiler warnings.
563 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
564 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
565 tm-sun3.h: Remove locally duplicated code for calling functions
566 in the inferior. The only differences were in the specific trap
567 vectors used and whether or not an fpu was present. These are
568 now handled by appropriate definitions of BPT_VECTOR and
569 HAVE_68881 respectively. Other minor obvious cleanups.
571 * valops.c: Correct a minor misspelling.
573 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
575 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
578 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
580 * stack.c (frame_command): Always print. Use new
581 frame_select_command to select a frame without printing.
583 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
585 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
587 * dwarfread.c: New file for DWARF debugging format support.
589 * elfread.c: New file for ELF object file format support.
591 * procfs.c: New file for SVR4 /proc (process file system) support.
593 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
596 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
598 * xm-m68k.h: New file for host machines with m68k cpu.
600 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
601 Add elfread.o and dwarfread.o to OBS.
603 * symfile.h: Add "elf" to list of supported formats in comment.
605 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
606 types to gdb, builtin_type_long_double, builtin_type_complex, and
607 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
608 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
609 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
610 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
611 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
613 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
614 call proc_set_exec_trap() to setup child to stop at first instruction.
616 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
619 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
620 supply_fpregset(), and fill_fpregset(), which are machine
621 dependent support routines for SVR4 /proc interface.
623 * utils.c: Add warning_setup() and warning(). Warning() behaves
624 the same as error() except that it returns normally rather than
625 jumping back to command level. Modules that don't want to call
626 warning() for some reason, but want to produce their own warnings,
627 can call warning_setup() to ensure compatibility with the way
628 warning() and error() deal with the terminal.
630 * symtab.c: Make internal errors produce more useful messages.
632 * tm-68k.h: Move code that is duplicated in almost every single
633 m68k based machine's configuration files to this common file.
634 Duplications in the configuration files still need to be removed
637 * infrun.c (child_create_inferior): System V versions must call
638 setpgrp() with no arguments, to comply with prototyping typically
641 * munch: Add support for SVR4 style nm output.
643 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
644 file specific fields from the partial symbol table structure and
645 replace them with a pointer to private data for each different
646 flavor of object file reader to initialize appropriately.
648 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
650 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
653 * mipsread.c (fixup_undef_type): New function. If a struct /
654 union / enum is defined in a header file but nowhere else used,
655 (by typedefing, pointer referencing or declaration) the mipsread code
656 builds the complete tree for the structure but leaves its code as
657 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
658 Guess its type based on the details of the members.
660 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
662 * infrun.c (wait_for_inferior): Check return value from
665 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
667 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
668 by my last edit to this routine.
670 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
672 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
673 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
674 the values before putting them into the dummy code. (From Peter
677 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
679 * configure.in: added ebmon target.
681 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
685 * Makefile.in: Roll VERSION to 4.2.
686 * README, TODO, WHATS.NEW: Update.
688 * core.c (core_open): Improve error message for bad file.
689 Pass .reg virtual memory address to fetch_core_registers to help
690 it find the registers in the core-file header.
691 * coredep.c (fetch_core_registers): Take new argument, use it,
692 and pass it to register_addr to locate the block of registers.
693 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
695 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
696 Sequent N_FN_SEQ like everybody else's N_FN.
698 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
699 * tm-i386v.h: #endif guck.
700 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
701 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
702 * xconfig/tahoe: Add REGEX, which seems to be missing.
704 * coredep.c: Add <sys/types.h> for SCOnix.
705 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
706 * printcmd.c (print_formatted): Flush output before disassembly.
708 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
710 * doc/refcard.tex (sec "Working Files"): consistent metavars and
711 other improvements, due to comments by François Pinard
712 (pinard@iro.umontreal.ca)
714 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
715 configure, and improvenets related to Pinard's refcard comments
717 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
719 Changes from Fred Fish:
720 * tm-68k.h (FPI_REGNUM): Add.
721 * infrun.c (child_create_inferior): flush stdout and stderr
723 * configure.in: Handle amigados, amix hosts and targets.
724 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
727 * values.c (show_convenience): Use printf_filtered.
728 * main.c (define_command): Check result of lookup_command for

734 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
735 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
736 * configure.in, tconfig/decstation, xconfig/decstation: Rename
737 dec3100 to decstation.
739 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)

752 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
753 generic routines for calling inferior functions.
755 * blockframe.c (inside_main_scope, inside_entry_scope): New.
757 * copying.awk: Filter formfeeds out of copying & warrantee.
758 Make them available as `show copying' and `show warrantee' also.
759 * main.c (print_gnu_advertisement): Advt `show' commands.
761 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)

764 core-file reading code.
765 * core.c (get_core_registers): Avoid coredump if no .reg section.
767 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
769 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
770 This avoids coredumps under `set print object on' in value_headof
771 (called erroneously by value_from_vtable_info) for `p &struct'
772 or `p *struct'. From Peter Schauer.
774 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
776 * Makefile.in: Roll version to 4.1.2.
777 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
778 size from BFD (but, FIXME, we don't yet read external nlists's and
779 convert them to internal nlists's before handling them -- we still
780 assume they have the same size and alignment.) Use SET_NAMESTRING
782 * exec.c (exec_file_command): Move dead coff-encapsulation code
784 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
786 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
788 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
789 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
791 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
793 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
794 * mips-xdep.c (store_inferior_registers): Don't try to
795 write the (pseudo) FP.
796 * mipsread.c (parse_partial_symbols): Improved algorithm for
797 setting pst->texthigh.
799 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
801 * doc/Makefile: make TEXINPUTS include . everywhere
803 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
805 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
806 vestiges of typevectors, which were for symsegs and are no longer
807 used. (From a question by Eliot Dresselhaus
808 <dresselh@RFT30.nas.nasa.gov>).
810 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
812 * dbxread.c, coffread.c: static-ize functions that were
813 gratuitiously external. (From Fred Fish.)
815 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
817 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
818 until it is large enough.
820 * dbxread.c (read_type): Handle error case slightly better.
821 Make complaint message not C++-specific.
823 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
825 * infrun.c (wait_for_inferior): Fix step/next so that you only
826 stop at the beginning of a new line. This fixes various problems
827 with for loops, nested if-else's and switch statements.
829 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
831 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
832 between symtabs and psymtabs become ordinary error()s.
834 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
835 properly, making "end pc" correct in shared lib psymtabs.
836 (From Guy Harris <guy@auspex.com>.)
838 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
840 * dbxread.c: Enable, but soften, const_vol_complaint.
841 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
842 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
843 should be file-scope, not global.
844 (read_struct_type): Remove ancient multiple-inheritance warning.
845 (read_range_type): Check base type, complain & patch if undefined.
846 * stack.c (frame_info): Demangle the function name in `info stack'.
849 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
851 * eval.c (evaluate_subexp_for_address): Don't use
852 TYPE_POINTER_TYPE directly (it might be zero if this type has
853 never had a pointer created before); use lookup_pointer_type.
854 * symtab.c (lookup_method_type): Arguments were swapped in all
855 callers, so fix it here. I'm amazed this worked at all!
857 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
859 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
860 "bss" rather than "data" symbols, but which still conflict.
863 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
864 * core.c (core_files_info): Shorten output.
865 * exec.c (exec_files_info): Ditto.
866 (build_section_table): Ignore zero-length sections.
867 * language.c, printcmd.c: Lint.
868 * language.h (get_frame_language): Declare.
869 * saber.suppress: update.
870 * stack.c (find_relative_frame): Remove complex code that was
871 #if 0'd, stick with simple code. Lint.

880 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
881 (Reported by Mark Peek <mark@imagen.com>.)
883 * solib.c (solib_map_sections): Relocate all sections, even
884 though only the text section's size is tracked. Mark ld_text
885 for eventual elimination as we generalize to N sections.
887 * infrun.c (wait_for_inferior): Don't check if the PC is in a
888 call_dummy if we were stopped by a random signal that is being
889 passed to the program. This produced wierd results when calling
890 functions in the inferior and signals (e.g. SIGALRM) were in use.
892 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
894 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
895 Bugfix from Paul Eggert <eggert@twinsun.com>.
896 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
897 * valprint.c (print_floating): Print 9 digits for IEEE floats.
900 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

906 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
910 * Makefile.in (VERSION): Set to 4.1.
911 * language.c (set_language_command): Print useful help message,
912 and restore the language string after giving help.
913 * valprint.c (typedef_print): Print typedef in C or M2.
914 * symtab.c (list_symbols): Use it.
915 * main.c (main): Avoid any output before (gdb) prompt when -q.
916 * language.c (set_language_command): Handle errors by restoring
917 the language string to its current state (fix from A. Beers).
918 * doc/gdbint.texinfo: Roll in information from README. Rearrange
919 "how to install" and "how to print the doc" stuff so it drops
921 * configure.in: Rename rtpc CPU to romp to match config.sub.
922 * README, WHATS.NEW, TODO: Update for gdb-4.1.
924 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
926 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
927 autoloading shared libs, copyright etc on GDB startup, clean up $_
928 and $__ index refs, set/show listsize and related updates to list
929 cmd. New host/target configs.
931 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
933 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
934 from main Makefile.in version definition
935 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
937 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
939 * doc/gdb.texinfo: merge new language-switching and lang-specific
942 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
944 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
945 compilers (which may lack stddef.h).
947 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
949 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
950 N_WARNING are the same except for the N_EXT bit, so just use their
951 values alone, rather than OR-ing them with N_EXT.
953 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
955 * mipsread.c (parse_lines): Deal with negative extended line
958 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
959 global symbol conflicts.
961 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
963 * .gdbinit: Move 'set complaints' to top, so it runs even in
964 case we aren't debugging GDB.
965 * language.c (_initialize_language): Fix type check and range
966 check documentation strings.
967 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
968 language.c can use it. (Though language.c should really not be
969 handling warnings/errors the way it does, FIXME.)
970 * symtab.c (lookup_primitive_type): const lint.
972 Bugfix from Peter Schauer:
973 * source.c (lines_to_list): Make signed, to avoid comparison
974 going unsigned and complaining that -3 is too high for 21 lines.
975 * stack.c (lines_to_list): Ditto.
977 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
979 * Makefile.in (HFILES): Add minimon.h.
980 (VERSION): Roll version number to 4.0.95.
981 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
982 New rules for building distributions. Normal distribution
983 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
984 one level up from here; it calls make-proto-gdb.dir to build a
985 directory `proto-gdb' which is an image of the release. The old
986 `gdb.tar.Z' rule still works too.
987 * config.sub, configure: Roll in latest from ..
989 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
991 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
992 new-target, and new-config chapters; fix minor typos; come closer
993 to usual GNU markup conventions for @file @samp @code @var.
995 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
997 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
998 * mipsread.c (parse_partial_symbols): Enter the name of all
999 structs/unions... into the psymtab so we can access them if the
1000 symtab is not read in.
1001 * mips-tdep.c: Remove some unneeded #includes.
1002 * xconfig/dec3100: Add HAVE_STRSTR.
1004 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1006 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1007 * c-exp.y, m2-exp.y: Lint.
1008 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.

1010 * mipsread.c (_initialize_mipsread): Avoid using
1011 builtin_type_void at initialize time.

1014 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1016 Merge multiple-language support, and partial Modula-2 support,
1017 from Andrew Beers <beers@cs.buffalo.edu>.
1019 * i387-tdep.c: New file, consolidates most 80387 support,
1020 and eliminates host dependency on double<->extended conversions.

1028 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1029 * dbxread.c (end_symtab): Use it.
1031 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd
1032 code for saving types of parameters with each function definition.
1033 * dbxread.c (define_symbol, function and parameter cases): Ditto.
1034 (read_dbx_symtab, case N_DEFD): Ignore.

1038 * coffread.c (end_symtab): Use allocate_symtab.
1039 (process_coff_symbol): #if 0'd for functions and params as above.
1040 (read_enum_type): Recognize Modula-2 BOOLEAN.
1041 * symtab.c (add_param_to_type): #if 0'd function to add a

1048 hex with local_hex_string for Modula-2 support.
1050 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test

1077 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1079 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1080 * expprint.c: Look up expression opcodes in language-specific

1113 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1115 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1116 entries are enclosed herein. Not all of these changes
1117 have been merged into the master GDB sources -- check the
1118 ChangeLog above here for the merge log.
1120 Mon Jun 3 17:05:45 EDT 1991
1122 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1123 operators were added, C specific operators and tokens
1124 removed. yylex() revamped to some extent. Still things
1125 missing from the grammar, such as sets.
1126 Tested for two weeks in GDB v3.5.
1128 Tue Jun 11 17:23:48 EDT 1991
1130 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1131 so they are built-in. Sort of a hack.
1133 Fri Jun 14 12:53:51 EDT 1991
1135 m2-exp.y Added range checking for numeric constants. Any numeric
1136 constant is assumed to be of builtin type INTEGER unless:
1137 (1) it is octal or hexadecimal, in which case it is a
1138 CARDINAL; (2) it is too big to fit into an INTEGER, in
1139 which case it is a CARDINAL.
1140 eval.c Added simple range checking for +, -, and * on integers.
1141 Doesn't work very well for *, since 6 * 1,000,000,000 =
1142 1,705,032,704, which fails the simple test of result >=
1143 first_operand, no matter in what order the operands are.
1145 Tue Jun 18 14:11:30 EDT 1991
1147 Broke the parser into parts, one containing the C grammar and the other
1148 containing code to be shared by all of the grammars.
1150 The following files no longer exist:
1155 The following files were added:
1157 c-exp.y (The C grammar)
1158 m2-exp.y (The Modula-2 grammar)
1159 parser-code.c (Code that is shared by the above grammar)
1163 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1164 now necessary to use the Bison compiler compiler, since it
1165 will generate function/variable prefixes other than yy.
1167 Tue Jun 18 16:47:49 EDT 1991
1169 symtab.[ch] Added the external variable working_lang, than holds the
1170 value of the current working language.
1171 Added the ennumerated type language_mode, with the values
1172 language_auto and language_manual, the former meaning that
1173 GDB sets working_lang as needed, and the latter meaning
1174 that the value of working_lang is totally under user
1176 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1177 REAL, BOOLEAN and CHAR. Also added the type codes
1178 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1179 utils.c Added set_language_command and show_language_command to
1180 implement the GDB support commands "set language" and
1182 expression.h A number of identifiers were added to the type exp_opcode
1183 to facilitate Modula-2 builtin functions, integer
1184 division, and array indexing.
1186 Wed Jun 19 13:25:58 EDT 1991
1188 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1189 if the language specified by working_lang requires the use
1190 of strict typing of expressions. Eventually, even this
1191 will be able to be changed by the user.
1192 Added the macro RANGE_CHECK, which evaluates to non-zero
1193 if the language specified by working_lang requires the
1194 checking of a value against the domain of its type.
1195 Eventually, even this will be able to be changed by the
1197 language.[ch] Predicates involving types (simple_type, ordered_type,
1198 same_type, integral_type, numeric_type, character_type,
1199 boolean_type, float_type) are added. These predicates are
1200 based on the current value of working_lang, and are handy
1203 Wed Jun 19 15:39:34 EDT 1991
1205 eval.c Added the function type_array_rank which computes the rank
1207 valarith.c Added the funtion value_bool, which when given a integer
1208 value.h value (ie. struct value *) as an argument, it returns a
1209 boolean value (ie. struct value *) true if that integer
1210 is non-zero, and a boolean value false otherwise.
1211 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1212 will print out properly.
1214 Wed Jun 19 16:36:34 EDT 1991
1216 valops.c Added the function value_capitalize, which returns it
1217 value.h argument capitalized if its argument is a lowercase
1218 letter, or the argument unchanged if its argument is not a
1220 valarith.c Added the function range_check_p, which returns non-zero
1221 value.h if its value argument is between the integral bounds upper
1223 Added the function range_check_enum_p, which makes sure
1224 that its value argument is a valid member of the domain of
1226 Added the function range_check_range_p, which makes sure
1227 its value argument lies between the upper and lower bounds
1228 of its type argument, which must be a ranged type.
1229 Added the function check_array_index, which range and type
1230 checks an index of an array.
1231 Added the function value_multi_subscript, which computes
1232 array[idx1,idx2...idxN], given a value array and an array
1233 of values representing indicies.
1234 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1235 unpack_long to work with TYPE_CODE_BOOL and
1238 Wed Jun 19 18:04:08 EDT 1991
1240 symtab.c Stored pervasive types in a structure and make
1241 lookup_pervasive_type() a lookup function that was based
1242 on working_lang. If lookup_pervasive_type() returned
1243 non-zero, then that value was returned (a fix, since
1244 before it simply wouldn't return the pervasive type.)
1245 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1246 non-zero if the language specified by working_lang means
1247 "conversion" when it says "cast".
1248 valops.c Added the function value_real_cast(), which performs a
1249 value.h *cast*, not a *conversion*, which is what value_cast()
1250 does when it can. In particular,
1251 value_cast(<float_type>,4) = 4.0, while
1252 value_real_cast(<float_type>,4) = some mess.
1253 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1254 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1255 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1256 and MIN on integral types. *NOTE*: These are currently
1257 hardcoded to work only if there are 8 bits per storage
1259 eval.c Made logical functions call value_bool to return a
1260 properly typed boolean value, based on working_lang.
1262 Thu Jun 20 11:55:27 EDT 1991
1264 valprint.c Types now print out in a Modula-2 fashion. This works for
1265 the cases when the type is printed out step-by-step, that
1266 is, it doesn't work when the name of a structured type
1267 (which includes the keyword "struct", etc.) is simply
1269 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1270 since type specifications in C and Modula-2 are very
1271 different. The C printing of a type is very recursive,
1272 whereas in Modula-2 it is generally very simple. C has
1273 type prefixes and suffixes, which have no real analogue in
1274 Modula-2. Maybe type_print() should call a language
1275 specific type printer. This is also advantageous if we
1276 compile GDB to exclude some of the languages. We'll just
1277 leave those functions out.
1279 Thu Jun 20 16:57:10 EDT 1991
1281 dbxread.c When reading the complete symbol table in (via
1282 psymtab_to_symtab()), the number and types of function
1283 arguments are added to a function type. define_symbol()
1284 calls add_param_to_type() to accomplish this.
1285 Assumption: when we come across a function definition
1286 (N_FUN symbol with an 'f' or 'F' in the name), its
1287 arguments will appear before another function definition.
1288 When a function is found, a pointer to its type is placed
1289 in the global in_function_type. Changes that
1290 add_param_to_type() makes are to this global.
1291 valprint.c The type of a function now includes (for Modula-2) the
1292 types of its parameters.
1293 eval.c Type checking and a check for the proper number of
1294 arguments is now done for function calls. Not sure of the
1295 impact this has on C++ member function yet.
1297 Thu Jun 20 19:58:48 EDT 1991
1299 valprint.c Rewrote the type printer. Broke it into two language
1300 specific parts, adding the functions type_print_m2() and
1302 An unfortunate consequence is this: if you debugging a C
1303 program in Modula-2 mode (why?), info types does not work
1304 well with regular expressions, since the types are printed
1305 out in Modula-2 terminology, but stored in C terminology.
1306 language.[ch] Added the functions new_type_last(), type_keyword(), and
1307 type_sep() to aid in the printing of typedefs.
1308 symtab.c Made the printing of typedefs as language independent as
1309 possible through calls to new_type_last(), type_keyword(),
1312 Fri Jun 21 11:50:26 EDT 1991
1314 dbxread.c Check all incoming ennumerated types. If it looks like
1315 Modula-2's BOOLEAN type, then change the type_code of the
1316 type to TYPE_CODE_BOOL so we can process it as a boolean
1318 valprint.c Replaced some of the 0x%x with calls to sprintf and
1319 hexformat() in val_print().
1320 language.[ch] Added the function hex_to_string(), which converts its
1321 integral argument to a hexadecimal number (format is
1322 language based) and returns the result as a string.
1324 Mon Jun 24 12:25:07 EDT 1991
1326 valprint.c Some functions call type_print_1() directly, instead of
1327 value.h using type_print(), so they can specify where (column) to
1328 print things. Since type_print() takes care of language
1329 dependence, that needs to be called first. Added a
1330 parameter depth to type_print() (so it is now like
1331 type_print_1). Changed type_print to type_print_at, and
1332 made type_print a macro that passes a depth argument of
1334 symmisc.c Changed all calls to type_print_1 to calls to
1336 Makefile.dist Made it possible to build GDB for a specific set of
1337 depend languages. Do this by passing a definition for the macro
1338 LANGS to make. LANGS should be a string containing a
1339 space-separated list of language names (ie. LANGS="c m2").
1340 The default is to build all languages. Note that grammar
1341 files must follow the naming convention of <lang>-exp.y.
1342 gdb.lang This holds the current value of the LANGS macro. It is
1343 examined every time make is called, and is updated if
1345 eval.c Added #ifdef _LANG_<lang> to these files.
1346 expread.c Still need to add them to dbxread.c and coffread.c.
1354 Mon Jun 24 16:33:11 EDT 1991
1356 language.[ch] Added the functions hexformat_pre() and
1357 hex_to_string_pre(), which take a prefix argument to
1358 include in the format string. Thus, hexformat_pre("08") will
1359 return "0x08x" (if the working language is language_c).
1360 Made hexformat() and hex_to_string() calls to the above
1361 with "" as the prefix argument.
1363 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1364 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1365 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1366 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1367 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1368 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1369 valprint.c, vax-pinsn.c
1371 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1372 calls to hexformat() and hex_to_string(). Format strings without
1373 the leading "0x" were ignored.
1375 depend Updated to take the above into account.
1378 Tue Jun 25 15:27:18 EDT 1991
1380 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1381 and type_check_t to keep track of the current state of
1382 range and type checking.
1383 main.c Added the variables range_mode, range_check, type_mode,
1384 and type_check to record the current state of range and
1385 type checking. Added initialization code to main().
1386 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1387 the above variables.
1390 Tue Jun 25 17:57:08 EDT 1991
1392 dbxread.c process_one_symbol() updates the variable (enum language)
1393 source_lang based on the extension of the filename
1394 contained in the N_SO sybmol that started this symtab.
1395 When end_symtab() is called, the value of source_lang is
1396 put into the language field.
1397 stack.c select_frame() sets working_lang (and possibly type_check
1398 and range_check) to the language field of the symtab
1399 associated with the frame that is selected if working_mode
1400 is language_auto. If working_mode is language_manual, a
1401 warning is printed and working_lang is not set.
1402 language.c Added the function set_type_range(), which sets the value of
1403 type_check and range_check (if their modes call for
1404 automatic setting) based on the current value of
1405 working_lang. A non-zero argument will cause the current
1406 settings to be output.
1409 Wed Jun 26 14:51:40 EDT 1991
1411 eval.c Added range checks on assignment.
1412 m2-exp.y Added the grammar for sets to the language. Currently,
1413 these do not do anything except print an error message.
1415 Wed Jun 26 17:01:04 EDT 1991
1417 m2-exp.y Added the ability for parse_number() to parse negative
1418 numbers. A global flag is set upon encountering a unary
1419 minus. This was done to make, for example, 1 parse as a
1420 CARDINAL, and not as an integer, per Wirth's examples in
1421 Programming in Modula-2 ed.4.
1422 valprint.c Added support for "set radix 2" by then setting
1423 output_format to 't'.
1424 eval.c Implemented range checking on subrange types. Added calls
1425 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1426 Implemented MIN and MAX for ennumerated types. The
1427 minimum value of an ennumerated type is defined by Wirth
1428 as the first identifier, and the maximum as the last.
1429 m2-exp.y Made octal numbers ending with "B" be characters and those
1430 ending with "C" be numbers, per Wirth's book. (p. 34)
1432 Thu Jun 27 14:11:52 EDT 1991
1434 stack.c select_frame() now only sets working_lang, it does not
1435 notify the user. If working_mode is language_manual, then
1436 a warning is issued once.
1437 main.c At the end of each call to execute_command(), working_lang
1438 is checked against the local static (enum language)
1439 current. If they differ and working_mode is
1440 language_auto, the new settings of language, type and
1441 range checking are printed out.
1442 stack.c Modified frame_info() to include the language of the
1443 current frame in the output of "info frame".
1444 language.[ch] Added the function language_str() which returns the name
1445 of the current language.
1447 Fri Jun 28 15:33:14 EDT 1991
1449 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1450 the language. INCL and DECL currently cause an error,
1451 since sets are not implemented yet. INC and DEC are
1452 implemented as PREINCREMENT/PREDECREMENT with one
1453 argument, and as ASSIGN_MODIFY with two arguments.
1454 eval.c Added type checking to the above cases.
1455 value.h Added not_lval_constant to the lval_type ennumerated type.
1456 not_lval_constant means that the value is a constant
1457 value; that is 3 or 'a' or TRUE, not as in a constant
1458 identifier. This is used to help coerce numbers such as 3
1459 to either signed or unsigned numbers.
1460 valops.c Added the function value_coerce_constants() which coerces
1461 constant integers as following: if one is a constant and
1462 the other is not, the constant's type is set to the type
1463 of the other argument. If both are constants and one is
1464 signed, the other is converted to a signed constant.
1466 Sat Jun 29 17:26:29 EDT 1991
1468 valarith.c Added a better range checker. It now checks range
1469 (successfully) on integral operations [+-] (signed and
1470 unsigned) for any C sized type. Still does not work well
1471 for multiplication.)
1472 int_in_size() returns an integer that is coerced to fit into
1473 specified number of bytes.
1475 Mon Jul 1 13:04:14 EDT 1991
1477 language.[ch] Added the function binop_result_type(), which returns the
1478 builtin (struct type *) type that would be the result of a
1479 binop on the two values V1 and V2.
1481 Wed Jul 3 19:22:53 EDT 1991
1483 source.c Extended source_info() to include the source language in
1484 the output from "info source".
1486 Fri Jul 5 13:48:52 EDT 1991
1488 utils.c Moved the support functions for the GDB set/show commands
1489 dealing with language into language.c.
1490 language.c Added the function language_info(), which displays info
1491 about the current working language, type and range check
1492 settings. Called via the GDB command "info language".
1493 Added an initialization routine _initialize_language(),
1494 that sets defaults for the language, type and range
1495 variables and sets up the new GDB commands.
1496 main.c Language setup moved to language.c.
1499 Mon Jul 8 10:10:22 EDT 1991
1501 valarith.c Debugged the range checker for arithmetic. Still does not
1502 work for multiplication very well.
1504 Mon Jul 8 12:40:37 EDT 1991
1506 language.[ch] Added the function value_true() which returns non-zero if
1507 its argument represents a boolean true value.
1508 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1509 check the truth of an expression.
1511 Thu Jul 11 12:51:34 EDT 1991
1513 language.[ch] Added the predicate structured_type(), which returns
1514 non-zero if the argument is a structured type.
1515 Added the predicate pointer_type(), which returns non-zero
1516 if the argument is a pointer type.
1517 eval.c Added the ability to do addition and substraction on
1518 pointers and integers. This case simply bypasses the
1521 Thu Jul 11 14:41:42 EDT 1991
1524 Added the symbol N_DEFD (0x4a) which is a definition
1525 module dependency that is used by the GNU Modula-2
1526 compiler and the linker. It is not important to GDB,
1527 except that [dbx|coff|mips]read.c should ignore these
1530 Fri Jul 12 16:07:00 EDT 1991
1532 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1533 0 in val_print(). Also added statements to the else part
1534 to coerce type (argument to val_print) to a pointer type
1535 if it is an "array of unspecified length".
1536 valops.c Added the function value_m2_string(), which returns a
1537 (value) value which is a constant string, whose type is
1538 (ARRAY [0..n] OF CHAR). The length field of the type
1539 structure is set to zero, so it will be interpreted as an
1540 "array of unspecified length".
1541 stack.c Moved the language/frame mismatch check to
1542 main.c:execute_command().
1543 main.c The working language is recorded each time
1544 execute_command() is executed. If working lang has
1545 changed during its execution, then the new
1546 language/type/range info is printed out for the user. If
1547 the working language does not match the language of the
1548 frame, a warning is issued.
1550 Sat Jul 13 16:16:39 EDT 1991
1552 eval.c Moved all the type-checking stuff for operators to
1553 language.[ch] language.c. This is so we can keep language-specific
1554 stuff (like for what type operators are defined) in
1556 language.[ch] Added the function binop_type_check(), which checks to see
1557 if its two (value) arguments are type-compatible with its
1558 opcode argument. The opcode should represent an operation
1559 involving an operator. Also added the macro function
1560 unop_type_check, which calls binop_type_check with a
1561 NULL second argument.
1562 expprint.c Added Modula-2 operators to the op_print_tab, so info
1563 expression.h break works correctly. Also added "op_string", which
1564 returns the string corresponding to the (enum exp_opcode)
1565 opcode that is its argument.
1568 Sat Jul 13 18:26:18 EDT 1991
1570 coffread.c Added code to record the type of function arguments with
1571 each paricular function. Code is very similar to that
1573 dbxread.c Moved add_param_to_type() to symtab.c
1574 symtab.[ch] Added function add_param_to_type() from dbxread.c
1576 *** NOTE: The above additions have not been tested.
1578 Mon Jul 15 12:50:47 EDT 1991
1580 langauge.[ch] Added the functions type_error and range_error, which work
1581 like error() except if the type/range mode is set to
1582 *_mode_warn, then they do not do a return_to_top_level(),
1583 but merely print a warning.
1584 Also changed [set|show]_[type|range]_command() to support
1585 the new "warn" feature.
1587 Thu Jul 18 17:50:54 EDT 1991
1589 mipsread.c Added code to record the type of function arguments with
1590 each particular function. Code is very similar to that
1593 *** NOTE: The above additions have not been tested.
1595 Fri Jul 19 11:19:10 EDT 1991
1597 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
1598 UMIN_OF_SIZE, which when given a size of a numeric type,
1599 return the maximum and minimum value it can hold. UMAX...
1600 and UMIN... return the result for unsigned types.
1601 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
1602 struct types. They call above macros.
1603 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
1604 avoid a name conlict with the above.
1605 c-exp.y Added range checking on numeric constants in
1606 parse_number() for completeness.
1607 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
1608 return 0 if working_lang is not language_c.
1610 Thu Aug 8 14:17:22 EDT 1991
1614 breakpoint.c Documentation strings of some commands changed to
1615 eliminate the references to the C language where
1618 Tue Aug 13 15:48:03 EDT 1991
1620 m2-exp.y Added qualified identifiers to the grammar. The semantics
1621 are slightly different from those of the GDB operator ::
1623 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
1624 type_exp, where type_exp is any valid type expression.
1626 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
1627 printcmd.c Modified ptype_command() so it actually parses the input
1628 (necessary for type expressions with scope qualifiers).
1629 Added the function ptype_eval() which expects an
1630 expression composed of one OP_TYPE element.
1631 *.[ch] Replaced all occurences of parse_c_expression with
1633 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
1635 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
1637 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
1639 Small fixes from Peter Schauer:
1641 * infrun.c (child_attach): Lint.
1642 * solib.c (find_solib): Handle shared libs version 2.
1644 Small fixes from David Wood:
1646 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
1650 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
1651 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
1653 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
1654 chars_per_line is at maximum (user typed `set width 0'). Fix
1655 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
1657 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
1659 * coredep.c: include ptrace.h where necessary.
1660 * mipsread.c(parse_lines): fix unsigned char problem that was
1661 messing up line numbers on SGI's and possibly other MIPS based
1663 * infrun.c (child_create_inferior): use better test to check
1664 return val from setpgrp().
1665 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
1666 for sgi/irix support.
1668 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
1670 * mipsread.c (parse_symbol): Put non-static procedures
1671 in the global block.
1673 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
1675 Patch together `text_start' and `text_end' for 29K port.
1677 * exec.c (exec_command): If NEED_TEXT_START_END, define the
1678 variables and set them based on the exec file.
1679 * am29k-tdep.c: declare text_start.
1680 * valops.c (call_function_by_hand): declare text_end.
1682 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
1683 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
1684 because machines that do this will also have to know to
1685 set NEED_TEXT_START_END. Besides, it was a redundant way to
1687 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
1688 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
1689 NEED_TEXT_START_END.
1691 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
1693 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
1695 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
1696 Pass MUNCH_DEFINE to munch whenever we run it.
1697 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
1698 format string; use 0x%x instead.
1699 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
1700 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
1701 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
1702 * inflow.c: Handle `short' process group IDs.
1703 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
1704 and check for ptrace errors.
1705 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
1706 (coff_symfile_init): Initialize text_bfd_scnum.
1707 (read_coff_symtab): Use it to find the text [and absolute?] sections.
1708 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
1709 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
1710 Merge target arm case with other "easy" cases. Add target
1711 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
1712 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
1714 * minimon.h, remote-adapt.c, remote-mm.c: Add.
1715 * munch: Cope with RT/PC putting fns in data segment.
1716 Restore ability to override `nm' by specifying MUNCH_NM.
1717 * xconfig/rtbsd, xconfig/ultra3: New host systems.
1718 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
1719 and remote-adapt. Remove encapsulated coff #define's (the
1720 support should go in BFD, and gdb shouldn't know or care).
1721 * tconfig/a29k-kern: Same, but for remote kernel debugging.
1722 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
1723 * tm-29k.h: Update BADMAG (though it should go away).
1724 Allow the register definitions to be overridden in another
1725 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
1726 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
1727 DUMMY_SAVE_GR96, for handling kernel calling conventions
1728 that use GR64+ rather than GR96+.
1729 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
1730 remote debugging of Ultra3 kernel. Includes tm-29k.h and
1731 overrides various things.
1733 * remote-mm.c (mm_attach, mm_wait): Handle attach like
1734 child_attach does, making a clean stop in the newly attached
1736 * remote-eb.c: Lint.
1738 * coffread.c: Make coffread independent of any particular
1739 variant of COFF. Avoid #include-ing any particular one except
1740 internalcoff.h. BFD now passes key values for symbol reading
1741 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
1742 and the symbol masks and shifts); use them.
1743 Remove obsolete end_of_text_addr.
1745 * exec.c: Remove unused include files.
1747 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1749 * Makefile.in (documentation targets): Pass $(M4).
1750 Bugfix from eggert@twinsun.com (Paul Eggert).
1752 * stack.c (down_silently_command): Check for stack existence.
1754 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1756 * Makefile.in (VERSION): Update to 4.0.3.
1758 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1760 * core.c (core_file_command): Print frame at coredump with
1761 its level number, by calling print_stack_frame.
1762 * frame.h: Add selected_frame_level, print_stack_frame.
1763 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1764 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1765 Change print_sel_frame and print_selected_frame callers to
1768 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1769 * symfile.c (free_named_symtabs): Ditto.
1770 * main.c (main): wrap_here needs an arg.
1771 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1772 (solib_add): Avoid noise.
1773 (solib_create_inferior_hook): Lint.
1774 (sharedlibrary_command): Move dont_repeat to here.
1775 * utils.c (error): Call wrap_here to force buffered output.
1777 Small patches from Peter Schauer:
1779 * coffread.c (start_symtab): Free any existing line_vector before
1781 (read_coff_symtab): Ditto for type_vector.
1783 * source.c (lines_to_list): New variable, replacing function.
1784 (all uses): Use as variable.
1785 (_initialize_source): Add 'set listsize' and 'show listsize'.
1786 * utils.c (lines_to_list): Remove function.
1787 * stack.c (print_frame_info): Use as variable.
1788 * defs.h (lines_to_list): Remove declaration.
1790 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1792 * breakpoint.c (insert_breakpoints): Restore warning about
1793 the program might be running in another process, but only for
1794 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1795 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1797 * utils.c (error): if error_pre_print is set, print the string
1799 * main.c (main, print_gnu_advertisement, print_gdb_version):
1800 Reformat legalese so it always prints, but acts as an "I'm here"
1801 message while symbols are being read. If any errors occur,
1802 print a few newlines to set off the message and start it at the
1803 left margin. Remove mention of "help" command, and don't yak
1804 about symbol reading.
1805 (catch_errors): Error string is now printed first in case of
1807 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1808 suggest the "help" command.
1810 * Makefile.in (VERSION): Set to 4.0.2.
1812 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1814 * .gdbinit: Remove useless "rr" command. Set complaints
1815 to 1 for people debugging gdb.
1817 * breakpoint.c, remote-vx.c: Reword strings printed by
1818 catch_errors callers.
1820 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1822 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1823 (Fix from kenc@viewlogic.com.)
1825 Fix some infrastructure to be able to cope with host and target
1826 machines with different sized basic types (ints, ptrs, etc).
1827 (Idea from pierre@la.tce.com (Pierre Willard).)
1829 * values.c (value_from_longest): Rename from value_from_long.
1830 Handle pointer types as well as integers, so that targets with
1831 different pointer sizes from the host can be accomodated.
1832 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1833 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1834 uses of value_from_long to value_from_longest.
1835 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1836 the correct pointer type to value_from_long{est}.
1838 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1840 * remote-vx.c: Remove obsolete code for calling functions via
1841 vxworks kludge interface (it referenced value_from_long).
1843 * valops.c (value_string): Find malloc with lookup_misc_func, not
1846 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1848 Make writing to files work properly. (Fixes to BFD are also needed.)
1850 * core.c (core_open): Open file ourselves, read or r/w, depending on
1851 write_files. Use bfd_fdopenr.
1852 * gdbcore.h (write_files): New variable.
1853 * exec.c (write_files): Define variable, add set&show for it.
1854 (exec_file_command): Use write_files to open for read or r/write.
1856 Make shared library reading happen automatically. These changes
1857 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1859 * inferior.h (stop_soon_quietly): Add to exported variables.
1860 * infrun.c (child_create_inferior): call solib hook, if defined.
1861 (child_attach): call solib hook, if defined.
1862 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1863 (find_solib): Use lookup_misc_func rather than hand-rolled.
1864 (symbol_add_stub): New stub for catch_errors.
1865 (solib_add): Avoid output if !from_tty. Catch errors rather
1866 than just calling symbol_file_add and bombing.
1867 (solib_create_inferior_hook): Interface with the target process
1868 to let it read and alloc shared libs, then figure out what it did.
1870 * core.c (validate_files): Fix typo, soften warning.
1871 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1873 * utils.c (fputs_demangled): Avoid duplicate printing if
1874 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1876 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1877 (Fix from pierre@la.tce.com (Pierre Willard).)
1879 * main.c (catch_errors): Change argument to a char * from an int,
1880 since a char * can point to a struct full of glop, but an int
1881 is not guaranteed to be able to hold a pointer.
1882 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1883 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1884 * core.c (core_open, solib_add_stub): Adapt.
1885 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1887 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1889 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1890 by adding .NOEXPORT target.
1892 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1896 * Makefile.in (VERSION): Roll to 4.0.
1897 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1899 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1901 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1904 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1907 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1909 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1910 reflect above name change
1912 * WHATS.NEW: correct pointer to refcard.
1914 * doc/gdb.texinfo: update New Features, Installing
1916 * doc/gdbint.texinfo: add short description of configure +template
1918 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1920 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1922 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1924 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1925 tar file, add dependencies for referenced doc files.
1927 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1929 * coffread.c, symfile.c, stack.c: saberized.
1931 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1933 * doc/refcard.tex: permuted Essential Commands sec
1935 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1937 set/show symbol-reloading
1938 default set complaints 0
1940 RET-repeat disabled after prompted long displays
1941 processID (attach) interpretation of 2nd GDB cmdline arg
1943 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1945 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1946 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1947 breakpoint.c, main.c: lint.
1949 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1951 Install new configuration scheme for GDB and friends.
1953 * config.sub: Translate ordinary names to three-part names.
1954 * configure: Use three-part names internally.
1955 * configure.in: Translate three-part names to filenames.
1957 * README, WHATS.NEW: Update for gdb-4.0.

1960 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1962 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1963 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1964 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1965 to single structures rather than arrays; when passing
1966 their address, use &. This avoids trouble with bdead compilers.
1967 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1968 instead. This avoids portability headaches.
1969 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1971 * source.c (open_source_file): Avoid ANSI const bdeath by
1972 skipping declaration and then casting result value.
1973 * tm-hp300bsd.h: Clarify comment.
1974 * utils.c (strstr): Result is const char *; ANSI bdeath.
1975 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1976 since system include file defines it differently from "defs.h",
1977 though the two are equivalent for our purposes.
1978 * tconfig/hp300bsd: Add m68k-tdep.o.
1980 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1982 * tconfig/sun*4: Remove warnings about system assembler.
1984 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1986 * mcheck.c: Avoid warning about undeclared abort fn.
1987 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1988 it causes recursive calls to error() when used in cleanups.
1989 To do so requires that we make it a function, so we do.
1990 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1991 * utils.c (do_cleanups): Remove the current cleanup from the
1992 chain *before* calling it, in case error() is called from it.
1993 The result won't be pretty, but won't be an infinite loop either.
1995 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1997 * dbxread.c (read_struct_type): Grok anon structs for C++.
1998 (vb_name, vptr_name): Null terminate these strings.
2000 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2002 Minor bug fixes from BSD Net2 gdb:
2004 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2005 returns 0, there is no previous frame.
2006 * breakpoint.c (commands_command): If !from_tty, don't call
2007 input_from_terminal_p().
2008 * dbxread.c (record_misc_function): Speed up slightly.
2009 (compare_psymbols): Ditto.
2010 * infcmd.c (do_registers_info): Take a second argument to
2011 determine whether to print float registers. "info registers"
2012 does not do so anymore. "info all-registers" does, now.
2013 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2015 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2016 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2020 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2021 executing_breakpoint_commands if we are interrupted by error.
2022 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2023 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2024 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2025 catch_errors() so we can setup the frame regardless of whether
2026 the shared libs work.
2027 * ieee-float.c (double_to_ieee_extended): Get exponent from
2028 right place in little-endian systems. From John Carey.
2030 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2032 * main.c: Remove unused terminating_signals and catch_termination().
2033 (long_options): Terminate with a zero element.
2034 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2035 (gdb_readline): Make call-compatible with readline.
2036 (init_signals): Improve comments re vfork vs. signal.
2038 * utils.c (prompt_for_continue): Use new gdb_readline().
2039 If we prompt for continuation, we don't let CR repeat the previous
2040 command, once we get back to a prompt. It's too easy to keep
2041 hitting CR, expecting "--more--" prompts, and have some long
2042 command start repeating on you.
2044 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2046 * blockframe.c (frameless_look_for_prologue): Speed up by
2047 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2048 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2049 Define two variants, one faster.
2050 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2051 and return zero, rather than giving an error.
2052 (setup_arbitrary_frame): Initialize the PC in the new frame.
2053 (skip_prologue): Add a second arg saying whether we're just
2054 checking for a frameless function or not.
2056 * core.c (core_open, core_close, core_xfer_memory): Move
2057 section table pointers and bfd* into the target_ops.
2058 (core_open): Allow errors in shared lib reading, etc.
2059 (core_files_info): Describe shared library sections.
2061 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2062 exec_files_info, set_section_command): Move section table
2063 pointers and bfd* into the target_ops.
2064 (add_to_section_table): Add BFD to section table.
2066 * target.c (target_xfer_memory, target_info): Pass target to
2067 xfer_memory and target_info functions.
2070 * gdbcore.h: Move struct section_table.
2071 * target.h: New home of struct section_table.
2073 * solib.c (solib_add): New argument is the target_ops whose
2074 section list is to be added to, if any. Reallocate the
2075 sections in that target to add any that come from shared libs.
2076 (throughout) so_sections renamed to sections.
2077 (solib_xfer_memory): Deleted.
2078 * tm-sunos.h (SOLIB_ADD): Add target argument.
2079 (SOLIB_XFER_MEMORY): Delete.
2081 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2082 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2083 from target_ops. It's the same on all targets. Add two section
2084 pointers to target_ops.
2086 * stack.c (find_relative_frame): Dump ancient algorithm for
2087 "down", just use handy "next" pointers.
2088 (frame_command): Don't error if there is no stack; let user
2091 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2092 modifies static state in the parent process; new_tty itself
2093 runs in the child and modifies the child's file descriptors
2094 to match the saved static state.
2095 * infrun.c (child_create_inferior): Call new_tty_prefork,
2098 * infptrace.c (child_xfer_memory): Add ignored target arg.
2099 * remote-eb.c (eb_xfer_inferior_memory): ''
2100 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2101 * remote-vx.c (vx_xfer_memory): ''
2102 * remote.c (remote_xfer_memory): ''. Rename from
2103 remote_xfer_inferior_memory.
2105 * main.c (main): Only try to attach "corefile" argument if
2106 it starts with a digit.
2108 * symfile.c (symbol_reloading): New "set/show" variable.
2109 (symbol_file_add): Shorten message about symbol reading.
2110 (add_symbol_file_command): Merge with add_syms_addr_command,
2111 since this should work on all targets now.
2112 (stop_whining): Default to zero, to shut up complaints
2113 about bad symbol tables on many systems.
2114 (free_named_symtabs): Just exit unless symbol_reloading.
2116 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2117 and add comment explaining shared library screw.
2119 * source.c: #if defined => #ifdef.
2121 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2123 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2125 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2127 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2128 (doc/Makefile knows how to make one for local config)
2130 * Makefile.in: use doc/Makefile for doc targets
2132 * doc/Makefile: GDB documentation now has its own Makefile
2133 doc/refcard.tex: renamed from "gdbrc.tex"
2134 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2135 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2138 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2140 * values.c (baseclass_addr): When reading target memory, use the
2141 length of the basetype, not the upper type. We've only malloc'd
2142 enough space for the basetype, leading to errors in free().
2144 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2145 ends up as a function specially, since we know the actual type of
2146 the pointed-to address. This (somewhat) fixes display of
2147 expressions that include misc_function_vector names. Try `cond 1
2148 !strcmp("a","b")' then `i b'.
2150 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2151 The child can be proceeded from inside wait_for_inferior in
2152 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2153 getting skipped in that case.
2155 * expprint.c (print_subexp): Use filtered output, since the
2156 subroutines we call use it, otherwise the output is horribly
2157 mangled, since output of wrappable stuff comes out late.
2159 * Makefile.in: Bump VERSION to 3.98.1
2161 * infrun.c (child_create_process): Use execlp to find the
2162 shell to exec our target program. This requires some fiddling
2163 with `environ' since there is no execlpe().
2165 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2167 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2168 Minor rearrangement of refcard permits two new make targets--
2169 gdbrc.dvi DVI output for refcard, using CM fonts
2170 gdbrc.ps PostScript refcard, using PS fonts
2172 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2176 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2177 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2179 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2181 * doc/gdb.texinfo: last changes for release.
2182 Minor typo and formatting fixes; incorporated most fixes remaining from
2183 filed mail commenting on earlier drafts.
2185 Added warnings: pipes don't work in run command;
2186 conditions are converse of assertions;
2187 step over fn without debug info goes to next fn;
2188 vars may have "wrong" values near fn entrance, exit
2190 Added example from Kingston on printing repeated nonadjacent values
2192 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2193 shell mode for signals
2195 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2196 doesn't sound so much like its parent "Stopping and Continuing"; also
2197 moved entries on continue to top of section, so they don't get lost.
2199 Improved installation directions in appendix, added manual formatting
2202 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2204 * configure.in: Remove xm.h and tm.h even if we aren't linking
2205 new ones, so "./configure sun4; ./configure none" does the right
2206 thing. Assume that alldeps.mak and depend are already built in
2207 srcdir, and avoid running "make" (particularly "make depend",
2208 which involves "gcc") from inside configure. Build Makefile
2209 directly rather than building Makefile.conf first.
2210 * configure: Regenerate with above changes.
2211 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2212 to 3.98. Revise gdb.tar.Z procedure to produce a file
2213 called gdb-$(VERSION).tar.Z but which unpacks into a
2214 directory called "gdb". Move non-source files out of
2215 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2216 (depend): Don't try to do "gcc expread.y".
2217 (expread.o): Update dependencies by hand.
2219 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2222 Fixed a variety of small typos that prevented info from formatting
2223 cleanly; altered too-long heading for GPL Appendix, as discussed
2224 w/RMS; Changed date on cover to July 91.
2226 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2229 (1) Applied some fixes due to comments from Larry Breed (easier ones
2230 through chapsec 5.2)
2231 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2232 it's broken in latest texinfo
2233 (3) Introduced *some* use of [] for optional arguments, where
2234 explanation is not simpler by listing cmd w arg and cmd w/out arg
2235 separately. Still not using @deffn.
2236 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2237 couple of headings are too long. Need patches to texinfo or revision
2240 * Partial update to README (which still needs work for this
2241 release!): (1) use of configure corrected for new script,
2242 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2244 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2246 * symtab.c (lookup_symbol): Don't complain right off about
2247 no debug symbols; use the misc function vector first.
2248 (list_symbols): Use misc function vector to find symbols
2249 that don't have debug info, and print them.
2250 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2251 PC range doesn't match symtab PC range, as it does on the
2252 MIPS because our symtab reading isn't perfect.
2254 * dbxread.c (dbx_symfile_read): Make warning about
2255 "no debug symbols" slightly nicer.
2257 * source.c (select_source_symtab): If "main" symbol exists,
2258 but decode_line_spec can't find line info, don't just return
2259 a zero; try other source symtabs or give an error.
2261 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2262 their low addresses first, then rip through fixing high addrs.
2264 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2265 <runene@ifi.uio.no>.
2266 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2268 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2270 * Minor, mostly mechanical, cleanup of doc subdir for clean
2271 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2272 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2274 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2276 Mostly MIPS and general symbol-reading fixups.
2278 * doc/gdbint.texinfo: Add documentation on symbol-reading
2281 * mipsread.c: Remove kludges around #include "ecoff.h".
2282 Remove redefinitions of a_magic, etc, no longer used.
2283 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2284 Fix global overview comments to match symfile.c protocol.
2285 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2286 (mipscoff_symfile_read): Eliminate unused code. Avoid
2287 sorting all the symtabs, when all we have read here is psymtabs.
2288 The symtabs are sorted as they are created anyway. Tell
2289 condense_misc_bunches whether we're mainline.
2290 (psymtab_to_symtab_1): Pass filename when recursing, to make
2291 stack trace more informative.
2292 (parse_partial_symbols): Assume cur_hdr as argument.
2293 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2294 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2295 the TYPE_NAME of char *, since that's done in symfile.c.
2296 (free_numargs, parse_symbol, add_symbol, add_block,
2297 shrink_linetable): Declare these fns void.
2298 (upgrade_type): Convert tree of if's to switch. Clean up
2299 bogus "off == 0" handling with a complaint. Avoid setting
2300 field bitpos and bitsize of array with lower and upper bounds.
2301 Check specified bitsize of elements against their actual type's
2302 bitsize, and complain if different. Complain about unknown
2304 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2305 (psymtab_to_symtab_1): Print names of subsidiary files that
2306 are being read in. FIXME, we read far too many files. This code
2307 is not the problem, the problem is in parse_fdr where the psymtabs
2309 (cross_ref): Result should indicate that we used one aux entry
2310 normally, or two if we encountered a "next" entry. This used
2311 to leave the caller pointing at the wrong aux entry.
2312 (add_symbol): If overflowed cur_block, reallocate it larger,
2313 chase all pointers to it, and complain(), rather than clobber memory.
2314 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2315 (new_field): Only allocate one field initially, not two.
2316 Pull ++ out of macro argument. Simplify.
2317 (_initialize_mipsread): Avoid initialization of importd
2318 global_psymbols and static_psymbols.
2320 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2321 to properly set pst->symtab; avoid searching for it.
2322 (symfile_fns): Improve comments, add a FIXME.
2323 * dbxread.c: Update comments to reflect symfile protocol.
2324 (read_ofile_symtab, end_symtab): Return the symtab.
2325 (psymtab_to_symtab_1): Set pst->symtab.
2327 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2328 whether we're mainline.
2330 * symfile.h (sym_fns): Remove unused sym_discard member.
2331 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2333 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2334 the environment variable is not.
2335 * infcmd.c (finish_command): Use filtered printfs.
2336 * cplus-dem.c: Add struct tags to a few unnamed structs.
2337 * valops.c (value_coerce_array): Improve comments.
2338 * valprint.c (type_print_varspec_suffix): Print array size only
2339 if greater than zero.
2340 * m88k-tdep.c: Shift some lines left by one space, that had
2341 apparently been trashed at some point.
2342 * TODO: More things to do, a few got done.
2344 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2346 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2347 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2349 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2350 * expread.y, findvar.c, symmisc.c: Ditto.
2351 * printcmd.c (address_info): Update printed forms of LOC_
2352 symbols. Elim LOC_EXTERNAL.
2353 (print_frame_args): Keep track of param stack offsets before
2354 re-looking up to find the local register param is kept in.
2356 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2357 Further integration of mipsread into gdb. Eliminate unused
2358 routines, duplicate declarations. Handle static symbols in
2359 psymtabs as well as external symbols. When reading symtabs,
2360 insert symbols into the correct block (global, static, or a local
2362 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2364 (mipscoff_symfile_read): Don't call select_source_symtab.
2365 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2366 rather than SYMBOL_VALUE.
2367 (parse_external): Comment clobbering of top_stack.
2368 (parse_partial_symbols): Update comments. Allocate and parse
2369 static symbols as well as external symbols. FIXME, enum values
2370 are not handled in this pass, but should be. Inline new_psymbol.
2371 Use SYMBOL_VALUE_ADDRESS.
2372 (psymtab_to_symtab_1): Read symbols into global static block
2373 by default (until enter some function's local block context).
2374 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2375 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2377 * source.c (select_source_symtab): Select a source symtab
2378 from either the symtabs or, failing that, the psymtabs.
2379 (list_command): Update error message.
2380 (forward_search_command, reverse_search_command): Use getc, not
2381 fgetc, for speed. FIXME, add comment about buffers that die if
2382 overrun by long line.
2384 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2385 by an entire word, which is not portable, if we have a 32-bit
2386 field. (Code in dbxread.c already turns such bitfields, if
2387 aligned, into ordinary ints, but fixing this will help for other
2388 symbol formats and for future changes.)
2389 * core.c (core_open): Handle ANSI const brain death.
2390 * utils.c (vprintf): Fix varargs typo.
2392 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2394 * findvar.c (find_var_value): Handle &function better.
2395 * TODO: Document work needed on &fn and &array.
2396 * printcmd.c (print_address_symbolic): New arg is the prefix
2397 to print if a name is printed.
2398 (print_address_demangle): Honor "set print address" now.
2399 Use new arg above to improve spacing of output.
2400 * valprint.c (val_print): When printing function pointers,
2401 print symbolic form too.
2402 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2404 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2406 * core.c (memory_error): Reword error msg to mislead less.
2408 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2410 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2411 parse_partial_symbols): Use newer BFD internals (external_filehdr
2412 and external_aouthdr), byte-swap the fields that we care about
2413 before using them, and make the file header data local to
2414 read_the_mips_symtab rather than global.
2416 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2418 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2419 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2421 * main.c (command_line_input): Flush stdout and stderr
2422 before every call to readline. This reportedly fixes a bug
2423 that comes up in Sys V running emacs-gdb and/or xxgdb,
2424 when stdin/out are pipes or sockets.
2426 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2428 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2429 Avoid declaring Makefile dependencies, because GNU Make stupidly
2430 tries to update it if we do.
2432 * coffread.c: Revise for minor changes to bfd internal coff
2435 * configure: If -template= is given a relative path, make it
2436 absolute before recurring in subdirectories.
2438 * configure, configure.in, Makefile.in: Install "configure" script
2439 as replacement for config.gdb.
2440 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2441 * README: Update for configure, mostly. FIXME.
2443 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2444 target config files that they are for the host. When the lines
2445 get copied into the Makefile, this makes it more obvious what's
2448 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2450 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2451 tabs, which end up in the disassembler output inadvertently.
2453 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2455 Make it compile cleanly in an ANSI GCC2 environment.
2457 * blockframe.c: <stdio.h>
2458 * cplus-dem.c: free takes a void *, ifdef __STDC__
2459 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2461 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2462 * stddef.h, stdlib.h: Remove these files.
2463 * symtab.c: Avoid declaring qsort, close.
2464 * symfile.c: Avoid declaring close.
2465 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2466 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2468 Assorted other changes.
2469 * dbxread.c: include "libaout.h", not "liba.out.h".
2470 * printcmd.c (print_frame_args): Set recurse properly for
2471 indentation of struct and array parameters.
2472 * valops.c (value_cast): Allow cast to void.
2473 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2474 single_step() in a target-independent fashion.
2475 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2476 set up to be ready to continue. This makes us target independent.
2477 * infptrace.c (child_resume): Remove call to single_step; now
2478 can single step a SPARC target of any kind.
2480 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2482 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2483 docn into separate sections---basically chapters, plus two loose
2484 pieces that can be configured to go in different places. This
2485 allows GNU m4 to preprocess the manual without coredumping.
2487 * Makefile.dist: tell TeX where to find texinfo.
2489 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2491 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2492 the new target "rdl-apps.texinfo" which captures the Makefile
2493 variable that records where to find the Readline libraries.
2495 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2497 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2498 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2499 * defs.h (const, volatile): Only define if not already defined.
2500 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2502 * README: Update for release 3.95.
2503 * config.gdb: Don't create readline dir in subdir builds.
2504 * main.c: Include with "..." form for non-system include files,
2505 so "gcc -MM" for "make depend" works.
2506 Include readline files with "...h" rather than <readline/...h>.
2507 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2509 * coffread.c: Undo minor damage done by Rich Pixley. Use
2510 different internal and external representations of COFF
2511 data structures. Use new BFD routines for swapping them in and
2513 * symfile.c (free_named_symtabs): Avoid freeing file names that
2514 are null or empty. Old i960 tools seem to produce files that
2515 claim to have empty names, causing each successive file read
2516 to blow away the previous one.
2517 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2518 Move deferred_stores to top of file, but don't separate its
2519 #define's from its variable. Add commentary.
2520 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2521 favor of keeping the (working) config.gdb. Move readline
2524 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2526 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2528 * infptrace.c (fetch_registers): no result, since now void.
2529 * tconfig/news: target depends on m68k-tdep too.
2531 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2533 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2536 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2537 applied various small fixes due to or inspired by RMS comments
2539 * doc/gdb.texinfo: finished using all RMS comments, save those for
2540 appendices on readline and cmd history (which are in other source
2543 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2545 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2546 chapter 9; (2) documented 'break' command's menu mode for
2547 overloaded names, in response to hgs problem report C++ p-31
2549 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2551 * doc/gdb.texinfo: (1) better introductory example; (2) more
2552 consistent use of @code, @samp, @file, @kbd throughout; small
2553 cleanups to first three nodes; (3) new "Contributors" node;
2554 (4) Appendix, Renamed Commands; (5) divert specialized startup
2555 instructions to "Targets" chapter for generic manuals, while
2556 leaving them up front for manuals specific to specialized
2557 environments; (6) apply fixes from RMS comments through chapter 4.
2559 * pretex.m4: modify explanatory text slightly (and redefine
2560 "regexp") to keep GNU m4 from complaining. (It still crashes
2561 later, but one step at a time...)
2563 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2565 * readline/readline.c (update_line): Avoid dereferencing a pointer
2566 before comparing it to its bounds. Saber caught this.
2567 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2568 and only set PC if tgetstr returned non-null. Saber caught this.
2570 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2572 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
2573 stuff for config manual) here where it counts; updated
2574 to use new subdir structure (gdb/doc/).
2576 * Makefile: generated from above via
2580 * gdbint.texinfo: added instructions on generating gdb.info* files
2581 locally for release. These are ordinary info
2582 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
2583 Makefile)---but due to use of texinfo 2, can't count on makeinfo
2584 to generate these, so we distribute them already formatted.
2586 * gdb.texinfo: included full Info node and menu crud (as generated
2587 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
2589 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
2590 put in comments-for-future gdb.info target (one day makeinfo will
2593 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2595 * gdb.texinfo: Updated to include new or old undocumented
2596 commands, at least the following (perhaps some others I forgot to
2597 record): info f, info float, info path, info program, info s, info
2598 set, info source, info terminal, info types, info user, set/show
2600 Also covered all recent GDB command renames for v4.
2602 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2604 * mipsread.c: Rather than keeping count of how many symtabs
2605 and psymtabs we have, for sorting purposes, count them when
2606 we need to sort. This fixes bug in rereading of symbol tables.
2608 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2610 * infcmd.c: renamed "info path" to "show paths"

2625 symtab.h, target.c, target.h: Lint.
2626 * core.c: setup and select frame after reading shared libs,
2627 else reading shared libs will clobber them. Lint.
2628 * utils.c (error): Force out any buffered wrap text.
2630 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2632 * remote.c: Remove decls of memory_insert_breakpoint
2633 and memory_remove_breakpoint, no longer used. (Suggestion of
2636 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
2637 to make it easier to interface to "configure"'d libraries.
2639 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
2641 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
2642 aliases for set/show print.

2772 Remove from_tty arg to mod_path.
2773 Put symfile_bfd in {coff,dbx}read.c not symfile.h.

3193 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3194 to the main file, as well as to include files. Also, put global
3195 functions into the global psymtab, to make "i fun" work.
3196 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3197 new psymtab for it has been read.
3198 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3199 a file, once a new symtab has been read for it.
3200 * mipsread.c: FIXME. We need to do the same for MIPS, but it

3202 queued to the psymtab list.
3204 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3205 If we have wiped out any old symbol tables, clean up at end of

3221 static psymbols list.
3222 (types_info): Restore this function from its untimely #if 0.

3244 is the first symbol read, even if not mainline.
3245 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3246 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3247 (set_section_command): New command ("section xxx yyy" -- should
3248 be renamed to "set section xxx yyy" FIXME) which sets the
3249 base address of a section of the exec file, overriding the
3250 virtual address that BFD reports.
3252 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3254 * exec.c: Add add_syms_addr_command to exec_ops, so you can

3259 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3260 for printing the float info is host-dependent, not
3261 target-dependent. FIXME.
3262 * i386-pinsn.c: Move #includes to top, remove useless ones.
3263 * i386-tdep.c: Don't bother including <.../reg.h> since we
3264 don't use it (and it doesn't exist on host systems).
3266 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3267 Convert negative numbers properly.
3268 (ieee_test): Make numbers really random; fix format arg.
3270 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3271 * core.c (core_detach): Unpush core_ops, which might not be on
3272 top. We used to just pop the top, which broke things. Don't
3273 need dont_repeat() any more.
3274 (core_file_command): Psst! Don't repeat it.
3275 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3276 * expprint.c (print_subexp): Avoid switch fallthru on
3277 BINOP_ASSIGN_MODIFY, so we can print += and such.
3278 * frame.h: Fix typo.
3279 * inflow.c (kill_command): After killing inferior, print our
3280 current frame in the core file, if we have one.
3281 (generic_mourn_inferior): When inferior dies, either select
3282 the current frame (in the new target, e.g. core file), or
3283 set both the current and selected frames to NULL.
3285 Changes from Peter Schauer.
3287 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3289 * Make all file names fit in 14 characters (sigh and damn!):
3290 mv hp300hpux-xdep.c hp300ux-xdep.c
3291 mv symmetry-xdep.c symm-xdep.c
3292 mv symmetry-tdep.c symm-tdep.c
3293 mv convex-opcode.h convx-opcode.h
3294 mv tm-vxworks960.h tm-vx960.h
3295 mv tm-vxworks68.h tm-vx68.h
3296 mv Makefile.srcdir Makefile.sdir
3297 mv gdb-int.texinfo gdbint.texinfo
3298 mv remote-sa.m68k.shar rem-m68k.shar
3299 mv remote-multi.shar rem-multi.shar
3300 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3301 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3302 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3305 * command.c (user_info_1, user_info): New command for listing
3306 the user-defined commands.
3308 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3310 * dbxread.c (really_free_pendings): Clear file_symbols
3311 and global_symbols after freeing them; otherwise, running
3312 this function twice (if it appears twice on the cleanup
3313 chain), we try to free things twice.
3315 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3316 based on text_addr (the address of text in core), not on addr (the
3317 offset between text in the .o file and in core). This change
3318 is from Peter Schauer.
3320 * main.c: Define ALL_CLEANUPS as a cast of zero.
3321 (return_to_top_level): Use it.
3322 (main): Do all cleanups after each command run as part
3323 of the gdb startup sequence. Also do all cleanups before
3324 entering the command loop, and every time we exit the command
3325 loop and reenter. Before, the cleanups from the startup sequence
3326 were being left undone until the first error!
3327 (command_loop): Rename do_nothing cleanup to command_loop_marker
3328 so we can see it easily when examining the cleanup chain.
3329 (init_signals): Add another do_nothing for signal handling.
3330 (quit_command): Only try to kill target if it has execution.
3331 Problems in the target stack got us into a state where
3332 inferior_pid was nonzero but none of the targets had execution.
3333 In this state you couldn't exit gdb.
3335 * dbxread.c: Two changes from Peter Schauer.
3336 (echo_command): Fflush output after an echo command.
3337 (show_history): Pass all args to cmd_show_list.
3339 * utils.c (init_malloc): Call mtrace to turn on tracing
3340 if the environment variable MALLOC_TRACE is set to a file name.
3341 * mtrace.c: Add source file which provides a log of every malloc,
3342 free, and realloc to a trace file.
3343 * mtrace.awk: Add source file which analyzes the trace file.
3344 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3345 (VERSION): Roll to 3.94.3.
3347 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3348 (check_duplicates): Don't bother with watchpoints.
3349 (set_raw_breakpoint): Comment about danger of this routine.
3350 (watch_command): Parse and eval all args before calling
3353 * solib.c (find_solib): Avoid error in referencing memory to
3354 see if any more shared libraries have been added. This is
3355 particularly useful if the target has terminated. Bug reported
3358 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3359 in bringing up 3.94.2 on the Sun-3.
3361 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3362 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3363 expression (in scope) before reenabling watchpoint.
3364 * signame.c (init_sigs): Add missing declaration of i, fix
3365 sys_siglist declaration.
3366 * source.c (list_command): Fixed range computation to use
3368 * stack.c (backtrace_command): Do not allow command if target has
3369 no stack, print informative error message.
3370 * target.c (target_command): Do not write into command line
3371 because this fails if the target command is used in a user defined
3372 command. [This change was enhanced by gnu to support any-
3373 unique-prefix matching on target names.]
3374 * valops.c (value_struct_elt): Avoid infinite loop on an
3375 erroneous attempt to print the member of function (try p main.p).
3377 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3379 * expread.y (name_no_typename): Avoid reduce/reduce errors
3380 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3381 Since the GDB parser really doesn't use name_no_typename in a
3382 name-only context, the parser can't tell the diff between
3383 names and numbers here. Avoid allowing a name_no_typename
3384 to be a NAME_OR_*INT to resolve the conflict.
3386 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3388 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3390 * valprint.c (val_print_fields): bitfield printing didn't handle
3391 byte order. Indirect through a few more fns to cope.
3393 * values.c (modify_field): also cope with byte order.
3395 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3397 Cleanup for release 3.94.2:
3399 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3400 include files. Roll version to 3.94.2.
3402 * coffread.c (init_stringtab): Read length into unsigned char
3403 array before swapping; don't assume 32-bit longs.
3405 * target.c (target_info): Don't bother with get_sym_file, just use
3406 the symfile global variable.
3407 * symtab.h, symfile.c (get_sym_file): Delete it.
3409 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3410 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3411 (read_type): Replace one more error() with complain().
3413 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3415 * i960-tdep.c: Fix copyright attribution.
3417 * config.gdb: Quote all backquotes in doublequotes. You can
3418 quote me on that. BSD 4.4 shell found this one.
3420 * infptrace.c (throughout): The third argument to ptrace is an
3423 * infrun.c (wait_for_inferior): When program has terminated, we
3424 have to call target_terminal_ours before we pop that target off
3425 the stack (e.g. before a call to target_kill or
3426 target_mourn_inferior). This fixes problem where a program
3427 terminates, then GDB stops for (tty output) and you have to type
3428 "fg" to the shell to resume it. FIXME: This code for what to
3429 do after termination really should be in normal_stop instead.
3431 * gdbcore.h (read_memory_check): Change declaration; it changed
3434 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3435 4.4 prereleases, this avoids a bug in their sgtty compatability
3437 * remote.c: Use terminal.h rather than hand-rolling the same.
3439 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3440 * utils.c (strsave, strstr): Fix arg types.
3441 * valprint.c (val_print): lint
3443 MIPS symbol table support from Per Bothner:
3445 * symfile.c (symtab_fns): Remove initializer table that needs to
3446 be hacked for each new symbol file format supported.
3447 (add_symtab_fns): New function, chains symbol table
3448 handlers into the global list.
3449 (symfile_init): Search this list.
3450 * symfile.h: Add next pointer, declare add_symtab_fns.
3451 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3452 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3454 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3455 symbol *). Thus, we no longer need the hack to trash
3456 pst->filename. Good, since that hack confused code in symfile.c!
3458 (reorder_symtabs, destroy_all_symtabs): Removed static
3459 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3460 Instead, the latter now uses a temporary array (stack-allocated
3461 from an obstack, and then freed).
3463 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3464 haven't been set in the outermost stBlock of a procedure. This was
3465 a problem with f77 binaries on Ultrix 4.?.
3467 (new_symtab, new_symbol, new_type): Continue changing code to use
3468 obstacks more and otherwise conform to dbxread internal style.
3469 Made the free_code of symtabs be free_linetable (as in dbxread)
3470 instead of free_contents. This implies memory leaks when reading
3471 a new symbol table, until the conversion is finished. Did change
3472 (struct symbol) and (struct type) to be allocated on the
3473 symbol_obstack. Blocks and blockvectors are among the things
3476 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3477 tested much, but it solved one problem (reported by Meissner), and
3478 cleans up some other things. The problem happened when an
3479 included file contains actual code (functions) and not just
3480 definitions. The mips coff is a little inconvenient there, since
3481 it may cause a procedure to be mapped to the wrong psymtab.
3483 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3484 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3485 this will need work for the new core paradigm.
3487 Opcode patches from the net:
3489 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3490 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3491 missing altogether - they are added here. From Bruce Bauman.
3492 * mips-opcode.h: The low mask for C0 instructions was too small.
3493 From Garrett Lau. I modified the fix to check the entire 32-bit
3496 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3499 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3501 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3503 * dbxread.c (read_type): Pointer subtraction (value_sub in
3504 valarith.c) sometimes failed because the types of the
3505 pointers being subtracted were not identical.
3506 These differed because dbxread.c was allocating pointer types
3507 using dbx_alloc_type+smash_to_pointer_type instead of
3508 lookup_pointer_type. I failed to find a justification for the
3509 former, so I changed it to use the latter. Similarly, I
3510 replaced smash_to_function_type by lookup_function_type,
3511 and smash_to_reference_type by lookup_reference_type.
3513 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3514 _initialize_mipsread): corresponding changes.
3516 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3518 * source.c (mod_path): Do tilde_expand on each component of the path,
3519 rather than on the (list of) paths as a whole.
3520 (print_source_lines): Set first_line_listed in addition to
3521 current_source_symtab and current_source_line. If the source was
3522 not findable, after a "dir" command to fix the problem,
3523 a "list" would get the wrong lines.
3525 While I was there... (gnu):
3527 * dbxread.c (read_type): Change error to complaint.
3529 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3531 First attempt at detailed understanding of symbol table memory alloc.
3533 * dbxread.c (dbx_symfile_read): Free our string table if we
3534 aren't the mainline. Free the "info" struct since we're done with
3536 (init_psymbol_list): Free any previously allocated psymbol lists.
3537 (): FIXME: Should realloc-down the psymbol lists when done reading
3538 the main symbol file?
3540 * symmisc.c (free_symtab): Free fullname field too.
3542 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3543 (REGISTER_ADDR): Make result type unsigned int.
3545 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3546 define REGEX must also define REGEX1 (its dependency).
3548 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3550 * tconfig/i960: No longer works, points you at vxworks960 or
3553 * xgdb.c, XGDB-README: Remove file. Users can get the much
3555 * Makefile.dist: Remove all trace of xgdb.
3557 * breakpoint.c (breakpoint_1): Pass demangle arg to
3558 print_address_symbolic.
3559 (clear_breakpoints): Remove unused function.
3560 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3561 (breakpoint_re_set): Use catch_errors to do them all anyway.
3563 * gdb-int.texinfo (Host versus Target): Add section on what is
3564 a "host" feature versus what is a "target" feature.
3566 * infcmd.c (path_command, path_info): Handle the PATH variable
3567 (object search path) as conveniently as the source search path.
3568 * environ.c (set_in_environ): Set some vars in GDB's environment,
3569 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3570 * source.c (mod_path): New function, from guts of
3571 directory_command, modifies a path. Used by path_command.
3572 (directory_command): Call it.
3573 * defs.h (strsave): Declare.
3575 * utils.c (sevenbit_strings): Add new printing option.
3576 (printchar): Use it.
3577 (strsave): Provide this handy helper routine.
3578 (set_width_command): Rename set_screen_width_command.
3579 (_initialize_utils): "set screen-width" => "set width";
3580 "set screen-height" => "set height"; add sevenbit-strings.
3582 * infcmd.c (do_registers_info): Print floating point registers
3583 in raw hex as well as float format, regardless of whether it is
3584 a "virtual" convertible register.
3585 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
3586 regs as a double, just in case it's being used that way.
3587 * values.c (unpack_long): Comment on array/function coercion.
3588 (unpack_double): Argument is in target byte order now. For
3589 integer arguments, just call unpack_long and float the result.
3590 * m68k-tdep.c: include defs.h for "const" handling.
3591 * remote-nindy.c: Use ieee-float stuff.
3592 (nindy_fetch_registers): Unpack double regs to host double, then
3594 (nindy_store_registers): Pack extendeds to host double, flip
3595 around by misusing unpack_double, send as target double.
3597 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
3598 zero, as when stopped at the first instruction of a process.
3600 * blockframe.c: Fix filename in comment (param.h => tm.h).
3601 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
3602 * tm-68k.h: Fix typos.
3604 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
3606 Changes from a bringup on the DEC Vax under Ultrix 4.0.
3608 * coredep.c (fetch_core_registers): Pass end-address of register
3609 section to register_addr as expected. Don't call supply_register
3610 if we'd just pass it garbage.
3612 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
3614 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
3616 * target.c (push_target, target_info): Cast enums to int for < or
3619 * stack.c (print_frame_info): Identify source file & line
3620 even if we can't print it.
3622 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
3624 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
3626 Clean up IEEE floating point support.
3628 * ieee-float.h: New file.
3629 * ieee-float.c: Write real routines to convert between host
3630 doubles and various target IEEE extendeds.
3631 * m68k-xdep.c: Eliminate assembler code for extended floats.
3632 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
3633 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
3634 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
3635 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
3636 double_to_ieee_extended.
3637 * i960-tdep.c: Define ext_format_i960.
3638 * m68k-tdep.c: Define ext_format_68881.
3639 * sparc-tdep.c: Define ext_format_sparc, though unused.
3640 * Makefile.dist (HFILES): Add ieee-float.h.
3641 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
3644 Obsolete the "coffstrip" program in favor of using BFD's strip.
3646 * nindy-share/coffstrip.c: Remove file.
3647 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
3648 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
3649 * tconfig/nindy960: Remove reference to coffstrip.o.
3651 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
3653 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3655 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
3656 * dbxread.c: Remove static symfile_bfd.
3657 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
3659 * inftarg.c (child_detach): Pop the child_ops vector if the
3660 detach is successful.
3661 * remote-nindy.c (nindy_create_inferior): Don't push a new
3662 nindy_ops since nindy uses the same one for execution and memory
3664 * core.c (core_ops): Use child_attach and child_create_inferior
3665 rather than default attach and create_inferior functions.
3667 Handle floating point registers in core files.
3669 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
3670 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
3671 This version untested since BFD doesn't yet support sun3 core
3673 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
3674 conventions. Fix comments and style. This version has not
3675 been compiled yet, since we have no HP inhouse.
3676 * core.c (get_core_registers): Look for two sections, ".reg"
3677 and ".reg2", and pass both to fetch_core_registers sequentially.
3679 Revise directory path yet again.
3681 * source.c (forget_cached_source_info): Not static any more.
3682 (init_source_path): New default source path is "$cdir:$cwd".
3683 (dir_command): Handle variable arguments ($cdir, $cwd).
3684 (source_info): Print "Compilation directory" rather than
3685 "Originally compiled in" to remind people of $cdir.
3686 (openp): If the path contains $cwd, use current directory.
3687 (open_source_file): If compilation directory is known, replace
3688 first $cdir in path with the compilation directory.
3689 (print_source_lines): Even if we can't print the lines, set the
3690 current symtab and line for future commands like "info source" or
3691 "breakpoint". Also, error message now contains the file name,
3692 line number, and file access error message.
3693 (_initialize_source): Fix help text to describe changes.
3694 * main.c (cd_command): Forget cached source info when we chdir.
3695 * utils.c (strstr): Add simple implementation.
3697 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
3699 * coffread.c (read_one_sym, init_linetable, init_stringtab):
3700 Byte-swap COFF symbol tables if necessary when reading them in.
3701 Use complain() to replace error message in one spot. Needs
3702 corresponding change in bfd/coff-code.h to make some symbol
3703 swapping routines non-static.
3705 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3707 Merge changes from Eirik Fuller, for UTek.
3709 * defs.h (errno): Add declaration.
3710 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
3711 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
3712 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
3713 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
3714 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
3715 declarations of errno.
3717 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
3719 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
3720 <rpc/rpc.h> and <rpc/types.h>.
3722 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
3724 * i960-tdep.c (examine_prologue): Add new argument limit,
3725 which stops the scan at the end of the prologue, or at the PC.
3726 This fixes a problem where it walks down into the code for the
3727 user's statements if that code looks like function prologues.
3728 Mark Fox and I have been bouncing this code back and forth, making
3729 small changes to it. Callers changed to match.
3731 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
3733 Cleanup for gdb-3.94 release final:
3735 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
3736 the .c files from vx-share and nindy-share, from the various
3737 macros, since they are not found via ALLDEPFILES.
3738 (SFILES): Add tm-i960.h.
3739 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
3740 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
3742 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
3743 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
3745 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
3747 * am29k-tdep.c: Add contribution line.
3748 (examine_prologue): Cache information about function prologues in
3749 the misc-function-vector to avoid lots of references over the
3750 serial line while examining instructions.
3752 * core.c (core_close): New function made from cleanup_core.
3754 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
3755 remote-vx.c, remote.c, target.c, target.h,
3756 Update target_ops vector to add attach, close, and load entries.
3757 Use add_syms_addr_command, not add_file_addr_command, for
3758 add_file. Break out close routine from existing code.
3760 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3761 they are in an obstack.
3762 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3764 (define_symbol): Add symbol type parameter; change callers;
3765 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3766 it to influence the symbol class on the i960.
3767 (define_symbol): Swap LOC_CONST's into target byte order.
3769 * exec.c (exec_close): New function.
3770 (exec_file_command): Call it.
3772 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3773 Fix byte order of frame pointer.
3774 (read_var_value): Result of 0 if var's value can't be found,
3775 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3776 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3777 (locate_var_value): Use read_var_value and use its lazy address
3778 as the location of the var's value. Lint.
3780 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3783 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3784 obsolete Intel versions in favor of vxgdb versions.
3785 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3786 code dealing with byte order of values, which Intel did in host byte
3787 order rather than gdb-4's target byte order.
3788 (i960_frame_chain_valid): Move to nindy-tdep.c.
3789 (examine_prologue, skip_prologue, frame_find_saved_regs,
3790 frame_args_address, leafproc_return, saved_pc_after_call,
3791 pop_frame): Add vxgdb versions from Mark Fox.
3792 (examine_prologue, frame_struct_result_address): Add code
3793 to deal with the saved value of G13 (struct return address
3795 (frame_args_address): Modify Mark's version to prefer the
3796 saved value over the current value in the topmost frame.
3797 Cache result in the frame info to avoid performance hair in
3799 (print_fault): Add gdb960 code for printing faults.
3800 (_initialize_i960): Actually call check_host.
3802 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3803 add stub routines. FIXME, these currently just return zero!
3805 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3806 (attach_command): Call target_attach, not target_open, now.
3808 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3809 (child_attach): Rename from child_open.
3810 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3811 don't confuse it with a zero step_resume_break_address.
3813 * inftarg.c (child_detach): Eliminate inferior_pid test.
3814 (child_files_info): Clean up message a bit.
3815 (child_ops): Use child_attach, not child_open, to attach.
3817 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3818 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3819 findvar.c to here, since it depends on the contents of the
3820 shadow_contents of breakpoints, but keep if #if 0 since it is
3823 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3826 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3827 (ptype_command, display_command): Eliminate have_inferior_p and
3828 have_core_file_p in favor of target_has_stack or
3829 target_has_execution.
3830 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3831 code for actually finding the values of arguments, though we still
3832 keep track of the maximum stack offset for use in printing unnamed
3833 arguments. Handle missing FRAME_ARGS_ADDRESS.
3835 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3836 (struct nindy_regs): Define registers passed to/from nindy.
3837 (nindy_fetch_registers, nindy_store-registers): Translate between
3838 nindy and GDB formats for the registers.
3839 (dcache_init): Statically allocate the cache, since it was being
3840 allocated by a malloc that was never freed anyway.
3841 (nindy_create_inferior): Error, not core dump, if no exec file.
3842 (nindy_before_main_loop): Use target_load, not target_add_file.
3844 * remote-vx.c (net_load): Specify large timeout for load
3845 requests. Allow user to break out with INTERRUPT.
3846 (net_break): Remove useless code, clean up. Change callers.
3847 (parse-args, skip_white_space, find_white_space): Clean up arg
3848 parsing to cope with quoted strings.
3849 (net_wait, net_quit): Never call error, just return status.
3850 (vx_read_register, vx_write_register): Cleanup status checking.
3851 #ifdef the code based on which CPU we are using (960 or 68k),
3852 FIXME, this should be completely general but it isn't yet.
3853 (vx_xfer_memory, vx_resume): Cleanup status checking.
3854 (vx_run_files_info): Improve message.
3855 (vx_load_command): Renamed from vx_add_file_command. Allow load
3857 (net_ptrace): Remove unused routine.
3858 (vx_wait): Adopt code from vxgdb960 to cope with broken
3859 connections to target machine and prompt to disconnect. Remove
3860 debug printouts. Map some EVENT_'s to SIGnals.
3861 (add_symbol_stub, vx_open): Print names of object files we found,
3862 and "ok" if we read their symbols OK. Clarify output in general.
3863 (vx_attach, vx_detach, vx_kill): Add these commands.
3864 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3865 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3866 "info files" output, and create_inferior, since we already have
3869 * stack.c (frame_info): Replace Frame_unknown with 0.
3870 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3871 (return_command): Pop until the PC matches as well as the FP,
3872 so it works even if the FP is shared with another function,
3873 as in "frameless" or "leaf" procedures.
3875 * symfile.c (load_command): renamed from add_file_target_command.
3876 (add_syms_addr_command): renamed from add_file_addr_command.
3877 (add_syms_command): Stub to call target_add_syms.
3878 (_initialize_symfile): Change command names and descriptions,
3879 add-file => add-syms, and load from alias to its own command.
3881 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3882 maybe_kill_then_create_inferior): Default for attempts to start
3883 a process, if one is already running, is to ask about killing
3884 it and retry if yes.
3885 (upstack_create_inferior): #if-0 it, strata obsolete it.
3886 (push_target, unpush_target, pop_target): to_close() a target
3887 before unstacking it.
3888 (target_info): Renamed from target_files_info.
3889 (_initialize_targets): Rename "i files" as "i target", accessible
3892 * target.h: Improve comments about the target_ vectored routines.
3894 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3895 Convert commenting style to standard GNU style.
3896 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3897 (SKIP_PROLOGUE): No longer a no-op.
3898 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3899 (*_REGNUM): Sort register numbers.
3900 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3901 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3902 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3903 are now 10 byte extendeds, not 8 byte doubles.
3904 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3905 for nindy versus vxworks targets. FIXME, this should possibly go
3906 in the target vector.
3907 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3908 frame_saved_regs and arg pointer with each frame.
3909 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3910 (FRAME_ARGS_ADDRESS): Use cached result.
3911 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3912 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3913 (PRINT_RAMDON_SIGNAL): Call print_fault.
3914 (POP_FRAME): Now works.
3916 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3917 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3918 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3919 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3922 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3923 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3925 * valarith.c (value_subscripted_rvalue): Avoid handling
3926 floats and doubles specially; it gave alignment errors. Lint.
3928 * valops.c (value_of_variable, value_of_this): Error if unknown
3931 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3932 to avoid alignment problems.
3933 (value_print): Handle unknown value address.
3934 (cplus_val_print): Two args are ignored; remove them. Change caller.
3935 (val_print): Use unpack_long rather than pointer-deref.
3938 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3939 to avoid alignment problems.
3940 (value_being_returned): Error if return value unknown.
3941 (set_return_value): Add bogosity warning, FIXME. *
3943 * TODO: A woman's work is never done.
3945 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3946 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3947 Add ieee-float.o to OBS.
3948 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3949 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3950 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3952 Changes to generalize the VxWorks RPC protocol slightly, to handle
3953 i960 as well as 68000.
3955 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3956 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3957 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3958 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3959 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3960 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3961 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3962 so they will move in target byte order rather than network
3963 byte order (happens to be the same).
3965 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3967 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3969 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3972 Add contribution lines to various files, showing where they
3975 * breakpoint.c (break_insn, check_break_insn_size,
3976 read_memory_nobpt): Remove to mem-break.c.
3978 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3981 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3982 entry has bad register number. This change is not
3983 tested in this release, FIXME.
3985 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3988 * value.h: Force value's contents field to be aligned to hold
3989 at least a double or a long long (if supported). This avoids
3990 doing bcopy's in and out of the contents field.
3992 (step_1): Avoid coredump under obscure circumstances when we
3995 * symtab.h (misc_info): Add field to misc function vector for
3996 any kind of cached information the target code desires. AMD
3997 29000 uses this to avoid repeating examine_function_prologue's.
3999 * coffread.c: Lint. Remove static symfile, read_section_header.
4000 core.c (have_core_file_p): Lint: remove.
4001 expprint.c (print_subexp): Lint.
4002 infptrace.c, valops.c, valprint.c: lint.
4004 Roll in changes from vxgdb-5.0.1:
4006 * symtab.h: Comment byte order of each address class. Add
4007 LOC_LOCAL_ARG for frame-relative args (960).
4008 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4009 symtab.c, symmisc.c: ditto.
4011 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4013 * remote.c (remote_resume): Error if resume with a signal.
4015 * symfile.c (prim_record_misc_function): Clear misc_info.
4016 (fill_in_vptr_fieldno): Check stub type of arg.
4018 * valops.c (value_cast): Avoid looking up names of types whose
4019 name we don't know, to prevent coredump. Sun CC produces typedef
4020 rtx and the name of *rtx is zero...
4022 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4024 Roll in changes from final AMD 29000 port (Tiemann).
4026 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4027 for ../include/a.out.encap.h. This might not work now that BFD
4028 is separately compiled. Instead, BFD support for encap will have
4029 to translate machine type 29k into the right COFF_MAGIC.
4031 * infcmd.c: Remove references to inferior_pid that aren't used
4032 in actual ptrace calls; use target_has_execution, etc.
4033 (have_inferior_p): Remove function.
4034 (program_info): Print target info rather than "process number";
4035 avoid gratuitous messages unless from_tty.
4036 (run_stack_dummy, finish_command): Set proceed_to_finish.
4037 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4038 main.c: Lint. Lose have_inferior_p().
4039 inferior.h (have_inferior_p): Remove, lint.
4040 (proceed_to_finish): Add flag to ask that all regs be saved
4041 by normal_stop, for the few commands that need it, speeding up
4042 serial I/O. Add comments to stop_registers.
4044 * remote-eb.c: Remove newline from breakpoint message we grep
4045 for. Never time out when running the user program.
4049 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4051 Roll in changes from vxgdb-5.0.1:
4053 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4054 symbol in its raw form, we are processing an unlinked ".o" file.
4055 See if the target environment has assigned it an address, using
4056 target_lookup_symbol (VxWorks does), and enter it into the symtab
4059 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4060 68k versions for a simpler version that assumes zero FP at bottom.
4061 Fixes bug of truncated stack reports.
4063 * target.h (target_lookup_symbol): Define this routine's args
4064 and result, finally.
4066 * target.c (nosymbol): Default routine for target_lookup_symbol.
4067 (target_default): Default lookup_symbol and call_function too.
4068 (files_info): Only print has_all_memory warning if a non-dummy
4071 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4072 vx_convert_from_virtual): If target does not have floating point,
4073 zero register "values", and avoid doing cross-net conversions.
4074 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4075 (vx_open): Rearrange code that attaches to target and reads
4076 symbols for all loaded modules, to work if some of the modules
4077 are not accessible. Add symbol_stub() and add_symbol_stub()
4078 as callbacks from catch_errors(). Allow connect attempt to be
4079 interrupted painlessly with ^C (FIXME, there are still some bugs
4080 if the interrupt happens during symbol reading.). Print
4081 final message with puts_filtered, since symbol messages are
4086 * main.c (catch_errors): Only print errstring if non-null.
4087 (command_loop): Avoid an ioctl per command to test ISATTY.
4089 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4090 (vx_xfer_memory): Return correct result!
4091 (vx_files_info): Indicate whether target has float or not.
4092 (vx_lookup_symbol): Complain, not error, if target gone.
4093 (vx_open): Print "Connected" msg before disabling immediate-quit.
4094 [FIXME: lookup_symbol and vx_open changes need testing.]
4096 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4097 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4098 contributor lines and update copyrights to 1991.
4100 Changes from an attempted H-PUX host port:
4102 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4103 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4104 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4105 * remote-vx.c: include <sys/time.h> for HPUX.
4106 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4107 "core_file_command" routine to BFD regime. May not work yet.
4109 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4111 * xgdb.c: Replace X10 version with some VJ version.
4112 (FIXME: Its copyright assignment is not on record.)
4113 * xgdb.c: Update include files to X11R4 (Xaw crud).
4114 (xgdb_display_source, create_text_widget): fix call to
4115 get_filename_and_charpos. Rewack source window stuff for X11R4
4116 (gleaned from include files, and "nm's" of binary libraries, since
4117 I had no doc available).
4118 (append_selection, append_selection_word): Disable with FIXME
4119 since R4 changed interface here.
4120 (create_buttons): Add back the old set of buttons.
4121 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4123 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4124 Roll VERSION to 3.94 (not yet final though).
4126 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4128 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4129 obstack_int_grow, obstack_int_grow_fast): Eliminate
4130 cast on left of assignment, which gives MIPS cc fits and is
4133 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4134 F_ALIAS. Use printf, not fprintf, when not passing a file
4136 (compare_opcodes): Check that identical instructions have
4137 identical opcodes, complain otherwise.
4139 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4140 was reported by Roland McGrath.
4141 (unimp): Only match if exactly zero instruction. (Roland)
4142 (branches and traps): Generate all variations of these
4143 instructions with macros, based on a single call that defines
4144 each condition name and its binary representation.
4145 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4147 * valprint.c (val_print_fields): Take, and use, format parameter.
4148 This means that "p/x struct" again prints the elements in the
4149 desired format. Changed callers.
4151 * stack.c (frame_info): Use filtered output, and indicate wrap
4152 points. Remove kludgy formatting designed to avoid line wrap.
4154 * utils.c (wrap_here): If the line is already full (because
4155 we had printed a long indent or long wrapped string), do an
4156 immediate newline-and-indent.
4158 * m68k-pinsn.c (print_insn_arg): Bugfix from
4159 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4160 instruction is incorrectly disassembled as bkpt #8.
4162 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4163 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4164 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4165 and then will dump core (sometimes). I traced it back to an
4166 uninitialized symfile_name in psymtab_to_symtab.
4167 (const_vol_complaint): Add quotes to message.
4168 (define_symbol): Only believe line number if gcc_compiled.
4169 Avoid allocating symbol if we will not return it.
4171 Add target strata support so that newly established targets go
4172 into their right place in the target stack (e.g. a new exec file
4173 doesn't wipe out the ability to access the running process).
4175 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4176 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4177 and initialize it properly in all the targets.
4179 * target.h: Document strata. Change return type of push_target.
4181 * target.c (nomemory): new function for dummy memory access.
4182 (tcomplain): Rename complain, now also used in symfile.c.
4183 (push_target): Push targets within strata. New return value shows
4184 whether new target is on top of stack or not. Always keep dummy
4186 (target_files_info): Ignore dummy target.
4188 * core.c (core_open): Warn user, and skip accessing file, if the
4189 core target is not the topmost target in the stack.
4190 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4193 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4194 target_ops, it doesn't belong there since we have no regs there.
4195 Change name of target from machine => memory to clarify.
4197 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4199 * Freeze version 3.93 for release.
4201 * Makefile.dist: Handle vx-share and nindy-share subdirs
4202 properly when building gdb.tar.Z.
4204 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4205 printed in various places, so I could change just one copy.
4207 * dbxread.c, coffread.c: Change references to bfd->iostream
4208 to cast to FILE *, now that BFD avoids needing types defined
4209 in other header files.
4211 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4213 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4214 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4215 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4216 (actually gcc -Wall).
4218 * dbxread.c: Remove first_global_sym, last_global_sym, since
4219 they are never referenced.
4221 * defs.h (baud_rate): Declare.
4222 main.c: Define it, and add the -b option to set it.
4224 * gdb-int.texinfo: Add text on how to define a new host or target
4225 architecture, prompted by Per Bothner's questions about MIPS
4228 * gdb.texinfo: Document "complaints". Change doc of -q since
4229 gdb no longer prints the copyright and blurb if you specify a file
4230 name to be debugged (just like Emacs). Add doc for Nindy-specific
4231 command line flags for specifying target serial port and such.
4232 Update copyright to 1991.
4234 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4235 has taken over for us the job of ripping up executable files. The
4236 crud caused Per Bothner's port to not compile.
4238 * infrun.c (normal_stop): Avoid printing "Program exited
4239 normally" if we are in batch mode. This allows a GDB which
4240 executes a program on a target system, to behave like a Unix
4241 command (input from stdin, output to stdout, no extraneous
4244 * main.c (main): Allow additional machine-dependent command line
4245 options to be specified with the ADDITIONAL_OPTIONS,
4246 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4247 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4248 processing to occur just before the main loop with
4249 BEFORE_MAIN_LOOP_HOOK.
4250 (main): If a "core file" argument is specified, and it is not a
4251 core file, try it as a process ID to attach.
4252 (symbol_completion_function): Attempt to cope with
4253 "show screen-" TAB, not very successfully. This needs more work,
4255 (batch_file): New function, returns whether we are reading
4256 commands from an interactive tty on stdin, or from somewhere else.
4257 Called by normal_stop since it doesn't get from_tty passed down
4258 to it like many commands do.
4260 * remote-nindy.c: Handle command line options for nindy
4262 (nindy_before_main_loop): Prompt user for tty name if they
4263 don't specify it before getting to the interactive command loop.
4265 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4266 and -r command line options. Also add hook before main loop
4267 to make it easy to specify a tty.
4269 * TODO: More things to do, one done.
4271 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4273 * dbxread.c: Make complaint() calls pass pointer, not struct.
4274 Add complaints about badly formatted C++ type information
4275 (const/volatile indicator, and parse errors resulting in
4276 error_type). Fix C++ virtual member fn comment.
4277 (read_struct_type): Avoid bumping pointer if we got a parse
4278 error; this prevents our walking beyond the end of a string.
4279 Terminate loop on null char as well as semicolon.
4280 (process_one_symbol): Fix the LBRAC fix so that it uses the
4281 last previous SLINE, FUN, or SO record's PC address. C++ debug
4282 symbols did not have SLINE records in a useful order compared
4283 to the LBRAC records.
4284 (define_symbol): Handle "catch" records.
4286 * symtab.c (check_stub_type): Added new complain
4287 `stub_noname_complain' and added a consistency check to
4288 keep the debugger from crashing when finishing from an
4289 exception frame. A real fix will be needed later.
4291 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4293 * infcmd.c (attach_command): Make global.
4295 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4296 but make them easy to comment out. Perhaps later they should
4297 be enabled by what CPU you configure for? FIXME.
4298 (VERSION): Roll to 3.93.
4299 (pinsn.o): Remove rule for obsolete file.
4300 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4302 Run down a problem that manifested by printing the wrong function
4303 name in stack traces of read_ofile_symtab. Turned out that the
4304 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4305 the LBRAC symbol with an address in the *data* segment, which
4306 blew our binary search through the blocks.
4308 * dbxread.c: Use the complain() facility consistently to bitch
4309 about problems in the symbol file we are reading.
4310 (finish_block): Add code to check the nesting of the blocks;
4311 complain and Procrust them to fit if wrong.
4312 (make_blockvector): Check the order of the blocks, complain
4313 [but don't cope] if wrong.
4314 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4315 symbols to be sure their PC value is greater than the last SLINE
4316 (line number) symbol we've seen, complaining and adopting the
4317 SLINE PC value if wrong.
4319 * symfile.h (struct complaint, complaint_root, complain,
4320 clear_complaints): Add.
4321 * symfile.c (complain, complaint_root, clear_complaints): Add
4322 facility to deal with non-fatal complaints and to regularize their
4324 (symbol_file_add): Clear complaint counters to allow new complaints.
4325 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4327 * dbxread.c (dbx_symfile_read): Remember the address and size
4328 of the string table for the main symbol file, so we won't read it
4330 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4331 to avoid reading the string table yet again. Lint.
4332 (throughout): Improve filtered output, including word wrap.
4333 (read_range_type): Improve Bothner's fix to handle other types too.
4335 * utils.c: Improve line wrap implementation. Handle unlimited
4336 width by making chars_per_line unsigned.
4337 (puts_filtered): New, easy, function.
4339 * defs.h (puts_filtered): add.
4341 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4342 call the identical sort_symtab_syms() in symfile.c instead.
4344 * expread.y: Suggest the `file' command rather than `symbol-file'.
4346 * command.h (enum var_types): Add zinteger for seroable
4348 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4349 nested if's into a switch.
4351 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4352 we did not stop because of a breakpoint (it must have been for
4353 some other reason, like a "stepi"), so don't print anything.
4355 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4356 doesn't include <sys/types.h>, old SunOS's require it for
4359 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4361 A test port of gdb-3.92.6 to the Sony NEWS.
4364 Don't normally link in remote- or vx stuff.
4365 Some of it doesn't compile, and it wastes space for 99% of the users.
4366 Remove reference to no-longer-used HAVE_VPRINTF.
4367 Fixed BFD_DEP typo to BFD_DIR.
4369 Fix cast in arg to bfd_h_getlong.
4370 Make char *prefix be const.
4371 Fix how certain range types are mapped into builtin unsigned int types.
4373 Remove 2 #includes. They cause errors (on Sony, at least),
4374 and aren't needed (they wern't in earlier versions).
4376 print_address_symbolic should never demangle labels
4377 (since it prints *assembler-level* labels).
4379 [This was superseded by the change to printcmd below.]
4382 Add some "volatile" return types to avoid warnings.
4383 If MISSING_VPRINTF add vprintf function and not just macro
4384 (since vprintf is used in printcmd.c).
4386 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4387 (The latter isn't grokked by some PCC-based compilers.)
4389 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4391 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4392 * nindy-share/coffstrip.c
4393 Added some forward declarations (otherwise, gcc complains
4394 about implicit extern redefined as static).
4396 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4398 Changes inspired by Per Bothner:
4399 * printcmd.c (print_address_symbolic): Take additional parameter
4400 specifying whether to demangle.
4401 (print_address): Pass in asm_demangle to control demangling.
4402 (print_address_demangle): New fn, takes explicit arg to control
4404 * utils.c: Add new vars demangle and asm_demangle, and let them
4406 (fputs_demangled): If !demangle, just print the argument.
4407 (fprint_symbol): If !demangle, just print raw symbol.
4408 * valprint.c (val_print): Call print_address_demangle rather than
4409 print_address, to cause demangling to depend on the global
4410 rather than assembler-level demangling setting.
4411 * WHATS.NEW, gdb.texinfo: Document.
4413 * main.c (show_command): Show all settings if no arg.
4414 (initialize_main): Make "info set" the same as naked "show".
4415 * command.c (cmd_show_list): Handle prefix commands in the
4416 list, and print the name of the setting as well as its English
4417 description and value.
4419 Allow gdb functions to specify where a line should wrap if it
4420 exceeds the size of a terminal line. Use it to make the output
4422 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4423 of the right size when screen width changes.
4424 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4425 (wrap_here): New fn, indicates a point in the output where we
4426 should wrap the line rather than just letting it overflow at a
4428 (fputs_filtered): Implement wrapping.
4429 (n_spaces): New fn, returns a pointer to N spaces.
4430 (print_spaces_filtered): Use n_spaces.
4431 * defs.h (n_spaces): Declare.
4432 * stack.c (print_frame_info): Wrap with 4-space indent after
4433 fn name and before filename and line number.
4434 * printcmd.c (print_frame_args): Wrap with 4-space indent
4435 before each argument name is printed.
4436 * valprint.c (value_print): Wrap with no indentation before
4438 (val_print_fields): Wrap with indentation relative to nesting
4439 level before each field name.
4440 (val_print): Wrap with nesting indentation before array elements.
4441 * command.c (do_setshow_command): Avoid extra newlines,
4442 wrap with 4-space indent around values printed, end with period.
4443 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4445 * breakpoint.c (breakpoint_1): Implement addressprint for
4446 "info breakpoints" display. Change file name and line number
4447 format to " at file:nnn" rather than " (file line nnn)".
4448 * gdb.texinfo: Document.
4451 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4453 Frozen for gdb-3.92.6 release.
4455 README, WHATS.NEW: Update for 3.92.6 release.
4457 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4458 coffread.o from configs since it is now built by default.
4459 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4460 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4461 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4462 from configs since it is now built by default.
4464 Makefile.dist: Update for release 3.92.6. Handle files that
4465 have been moved to ../include, ../getopt, or ../bfd. Add
4466 saber.suppress and tests directory. Add config.status to
4467 the release (it will say "none").
4469 coredep.c: Minor formatting fixes.
4471 These changes were made in early December but only checked in now:
4472 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4473 nindy-share/nindy.c: lint
4474 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4475 register values coming back from the target; we store values
4476 in target byte order everywhere.
4478 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4480 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4482 * valprint.c (cplus_val_print, val_print_fields): New functions,
4483 which print C++ objects. They conspire to avoid printing a
4484 virtual base class more than once, following all the twists and
4485 turns of C++ virtual base rules.
4486 (val_print): Call the above rather than do it by hand.
4488 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4489 symbol file, not for added files like shared libs. This really
4490 needs to be generalized to a timestamp per file.
4492 * core.c (cleanup_core): Avoid coredump if no core file.
4494 * config.gdb: Accept -host or -target in place of +host or
4497 * coffread.c (find_linenos): Avoid desupported BFD interface
4498 to line numbers. We still read them manually rather than using
4499 BFD's "generic" features.
4501 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4503 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4505 * Makefile.dist: Eliminate use of $< in explicit targets.
4507 * readline/Makefile: Use $< rather than $*.c, which does not
4508 include the VPATH in GNU Make.
4510 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4511 copies of tconfig/i960, added for global configuration
4512 compatability. All i960 versions can read both coff and b.out.
4514 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4515 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4518 * TODO: Think of more things to do.
4520 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4522 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4523 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4524 64-bit float conversion.
4526 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4527 equivalent to sun?os4 so global config works.
4529 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4531 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4533 * main.c: Only declare linesize once; declare pagesize not at
4534 all, since it is never used.
4535 (main): Clear newly allocated line before it is used.
4537 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4539 Further stabilization for the Intel 960.
4541 * Makefile.dist: Parameterize the location of the "include"
4542 and "bfd" directories, as well as "getopt". Add symfile.c.
4543 Link in both dbxread and coffread. Fix up "make depend" to
4544 rewack the locations of include, bfd, and getopt in its output.
4546 * README: Document moving include files, improve some of
4549 * coffread.c: Move common code out to symfile.c. Change
4550 symbol_file_command style interface to use new *_symfile_init
4551 and *_symfile_read interface under BFD. Use BFD internal
4552 info to locate line table, symbols, etc.
4554 * core.c (core_fetch_registers): Rename to get_core_registers
4555 to avoid confusion with fetch_core_registers.
4556 (register_addr): Move to coredep.c, which is already machine
4557 dependent. This leaves core.c pretty clean of dependencies.
4559 * coredep.c (register_addr): Accept this routine from core.c.
4561 * dbxread.c: Move common code (with coffread.c, etc) into new
4562 symfile.c. Each psymtab now contains a pointer to the
4563 format-dependent function that knows how to read it in. Make
4565 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4566 (process_one_symbol): Add code to complain about a "compiler bug
4567 we muzzle here", if we actually see it.
4569 * eval.c (evaluate_subexp): Insert missing "break" statements
4570 in code that determines whether a variable is an lvalue in
4571 memory, register, or whatever. I detected this via a compiler
4572 bug in which it *almost* mashed out the whole switch statement.
4574 * gdb-int.texinfo: Add minor sections on configuring gdb for
4575 release, and about the README file.
4577 * infcmd.c (registers_info): Fix formatting somewhat. Still
4578 not as pretty as before, but it handles byte swapping.
4580 * remote-nindy.c: If data cache routines are interrupted while
4581 waiting for the remote end, be sure that any uninitialized cache
4582 blocks are on the free list, not on the valid list!
4584 * symfile.h: Flesh out this header file with all the various
4585 routines and variables that have been merged in from dbxread.c
4586 coffread.c, and symtab.c to symfile.c.
4588 * symfile.c: New file, containing code common to dbxread.c,
4589 coffread.c, and some code from symtab.c. All generic code for
4590 reading symbol files should be in here now.
4591 (unrecord_misc_function): Remove unused function.
4593 * symtab.h: Remove file-reading things to symfile.h.
4595 * symtab.c: Remove file-reading things to symfile.c.
4597 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
4598 to decode i960 fault types.
4600 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
4601 target.c: Change type of the "resume" function from int to void,
4602 since its result was never used.
4604 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
4606 * main.c: Replace "stupid" with "caution"; you now "set caution
4609 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
4611 * infcmd.c (do_registers_info): Call val_print to deal with the
4612 byte order of the registers being printed. FIXME, this makes
4613 the formatting of the output uglier.
4615 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
4616 defined, call it for signals the debugger doesn't itself use.
4617 The i960 uses this for more detailed fault information.
4619 * remote.c (remote_open): If arg is null, print help rather than
4622 * sparc-xdep.c (register_valid): Avoid declaring size, since
4623 various modules will think of various sizes depending on the
4624 architecture of their tm-file. FIXME, we need protection against
4625 actually entering one of those modules, which would clobber
4626 storage if not for the target architecture compiled into gdb.
4628 * stack.c (up_command, down_command): Always print the frame
4630 (up_silently_command, down_silently_command): New commands
4633 * i960-pinsn.c (reg), i960-tdep.c: Lint.
4635 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
4636 more parameters than it used to.
4638 * findvar.c (registers): Increase slop to 256 bytes, which should
4639 protect us against even most RISC machines with large register
4641 (locate_var_value): Move declaration inside related ifdef.
4643 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
4644 throughout, to avoid throwing away buffered input from the board.
4645 (nindy_wait): Supply_register takes addr_of_value, not value.
4646 (i960_print_fault): Renamed from i80960_fault.
4647 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
4648 (nindy_store_registers): Avoid regs_changed stuff, just stuff
4650 (nindy_create_inferior): Don't bother to write PC_REGNUM since
4651 we can set the PC in the call to proceed(). Unpush nindy_ops
4652 before pushing it on top, to avoid message to user. Eliminate
4653 commentary from Unix machines that just misleads here.
4654 (reset_command): Fix error message to suggest target command.
4656 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
4658 Release 3.92.5 as frozen.
4660 Stabilize the merged release...with help from lint, Saber C,
4663 Everywhere: Add include files needed to declare return types
4664 of functions called.
4666 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
4668 * breakpoint.h: Add undeclared breakpoint functions, and some
4669 functions for display handling since I couldn't think of a better
4672 * breakpoint.c (insert_breakpoints): Make code for disabling
4673 shared library bkpts more likely to work. It's used when we
4674 rerun a program and stop before the shared library has been
4676 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
4677 cast from pointer, so it squeezes through catch_errors.
4678 (bpstat_stop_status): Fix logic broken some time ago. We now
4679 always create a bpstat if the stop address matches a breakpoint,
4680 even if we don't stop there -- just like the old code used to do
4681 before I got my fingers into it (sigh).
4682 (breakpoint_1): Print "ignore count" after "stop only if"
4683 condition, since that's how it actually works.
4684 (mention): Handle watchpoints as well as breakpoints.
4685 (watch_command): use set_raw_breakpoint and mention to do most
4686 of the work (and initialize all the fields!). Only pass one
4687 arg to parse_c_expression, since that's all it takes.
4689 * command.c (not_just_help_class_command): Rename arg to args
4690 since we ignore "unused argument" warnings on vars named "args".
4691 inflow.c (child_terminal_info): ditto.
4692 infptrace.c (kill_inferior): ditto
4693 main.c (catch_errors, version_info, quit_command, pwd_command,
4694 source_command, dump_me_command, editing_info,
4695 set_history_size_command, set_history, show_history,
4697 stack.c (locals_info): ditto
4698 target.c (target_files_info): ditto
4699 valprint.c (set_input_radix, set_output_radix): ditto
4701 * core.c: Remove old variables for handling core and exec file
4702 sections (data_start, data_end, stack_start, stack_end,
4703 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
4704 text_end, exec_data_start, exec_data_end, text_offset,
4705 exec_data_offset, data_offset, stack_offset). They're
4706 superseded the more general build_section_table and
4708 (get_exec_file): Mention the `file' command.
4709 (read_memory_check): Rename to memory_error, and only call it
4710 in the case of an actual error.
4711 (read_memory, write_memory): call memory_error.
4712 (core_fetch_registers): Register section name is ".reg".
4714 coredep.c: Remove a bunch of crud now that all this file does
4715 is pull the registers out of a core file.
4716 (fetch_core_registers): Rewrite to actually work, I hope.
4718 dbxread.c: Use a.out.gnu.h, not system a.out, now.
4719 Replace index() with strchr(). Remove all the pre-BFD macro
4720 definitions for accessing the symbol file.
4721 (struct dbx_symfile_info): Encapsulate the information that
4722 dbx_symfile_init needs to pass to dbx_symfile_read in this
4725 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
4726 dbx_symfile_discard): Rearrange symbol file reading to divide
4727 the format-specific part from the format-independent part,
4728 leaving the format-independent part such as file name expansion
4729 and opening in symtab.c. This replaces
4730 partial_symbol_file_open and partial_symbol_file_read.
4731 Symbol_file_read, add_file, add_file_target_command,
4732 add_file_addr_command move to symtab.c. Pass an explicit
4733 "mainline" flag for when reading the main symbol table, rather
4734 than relying on the offset address to be zero or nonzero.
4736 (dbx_symfile_read): Don't allow void *'s to be printed as
4738 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
4739 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
4740 macro" debug version really work.
4741 (read_dbx_symtab): Remove unref'd parameter inclink.
4742 Avoid swapping N_SLINE symbols, for speed.
4743 Merge N_TEXT!N_EXT case with the other external symbol
4744 definitions' case. Add comments.
4745 (start_psymtab): Allocate the symfile name in the psymtab on
4746 the psymbol_obstack, rather than using the caller's storage.
4747 (end_psymtab): Only allocate a dependencies list if there are
4749 (psymtab_to_symtab_2): Use BFD when reopening file to read
4750 its symbols for real.
4751 (read_struct_type): Add FIXME comments where it needs work
4753 (read_huge_number): Add FIXME about overflows.
4754 (read_range_type): Add FIXME about comparing a long to 1<<32.
4756 * coffread.c: Minor changes to move things closer to the new
4757 regime with symtab.c and dbxread.c Major work is still needed
4760 * exec.c (exec_file_command): Remove old variables (see core.c
4762 (xfer_memory): If memory transfer is right at the end of a
4763 section, don't lose.
4765 * findvar.c (get_saved_register): If value is in a real
4766 register, LVAL is lval_register, not lval_memory.
4768 frame.h: Declare print_sel_frame and record_selected_frame.
4770 gdb-int.texinfo: New file, for GDB internals documentation.
4771 Very simple, unformatted doc of cleanups is there for now.
4773 gdbcore.h: Remove obsolete variables that described a.out
4774 section addresses and offsets. (See core.c above.)
4775 Declare fetch_core_registers and registers_fetched.
4777 getopt.c: Declare char *alloca(); even on SPARC.
4779 infcmd.c (run_command): Call target_kill rather than
4781 (step_command, next_command, stepi_command, nexti_command):
4782 Declare from_tty parameter even though we don't use it.
4783 (run_stack_dummy): argument BUFFER is a char array, not
4784 a pointer to REGISTER_TYPE.
4785 (finish_command): using_struct_return needed a value *,
4786 not a struct symbol *.
4788 * infptrace.c (child_xfer_memory): To avoid dependency on
4789 where sections are in memory, try PT_WRITE_D and if that fails,
4790 try PT_WRITE_I. Most Unixes don't care which you use.
4792 * infrun.c (step_resume_break_shadow): Change to array to
4793 match other breakpoint shadow storage.
4794 (clear_proceed_status): Pass address of bpstat to
4795 bpstat_clear, not the bpstat itself.
4796 (child_create_inferior): FIXME comment about if the child
4798 (start_inferior): Remove old function.
4799 (child_open): Use target_kill rather than kill_inferior.
4800 (wait_for_inferior): Ditto.
4801 (insert_step_breakpoint, remote_step_breakpoint): Use
4802 new step_resume_break_shadow.
4804 * inftarg.c (child_wait): If all child processes die,
4805 pretend that the one being waited for exited with signal 42.
4807 * main.c (command_line_input): When scanning for comments,
4808 don't coredump on unclosed quotes.
4809 (quit_command): Use target_kill rther than kill_inferior.
4810 (_initialize_main): Rename class_user from "user" to
4813 * printcmd.c (print_command_1): Initialize "fmt" if no format
4814 is specified by the user.
4815 (print_frame_args): Only add to args_printed if we are
4816 actually fetching args from the stack (avoiding undefined
4818 (_initialize_printcmd): Remove bogus \{ from string.
4820 * remote-eb.c (eb_open): Avoid coredump on no argument.
4822 * remote-nindy.c: Bring out of Intel environment into new
4823 target environment. Remove all conditional compilation on
4824 I80960. Massive hacking throughout.
4825 (nindy_xfer_inferior_memory): New routine stolen from
4827 (nindy_create_inferior): New routine pieced together, probably
4828 not quite working yet.
4829 (nindy_ops): New target_ops struct for nindy.
4831 * remote-vx.c: Use write_memory rather than target_write_memory
4832 to get error checking.
4833 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4835 (vx_create_inferior): Use target_terminal_ours...
4837 * signame.c (_initialize_signame): Always initialize, since
4838 we need the table for things other than psignal.
4840 * solib.c (solib_add): Use symbol_file_add, not add_file.
4841 (solib_address): Return boolean result rather than struct
4842 pointer which nobody else knows the type of.
4844 * sparc-tdep.c, valops.c: Use write_memory rather than
4845 target_write_memory, to get error checking.
4847 * stack.c (locals_info, catch_info, args_info,
4848 get_selected_block, frame_command, up_command): Use
4849 target_has_stack, rather than have_inferior_p or
4852 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4854 * symfile.h: New file, defining the interface between the
4855 generic and object-file-specific symbol reading code.
4857 * symtab.c: Move generic symbol-reading interface to symtab.c,
4858 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4859 table to map BFD targets to symbol-reading modules in GDB.
4860 Change index to strchr.
4861 (lookup_struct_elt_type): Use error() rather than hand-made
4862 simulations thereof.
4863 (lookup_partial_symbol): Speedup slightly when length == 0.
4864 (symbol_file_add): New function.
4865 (symbol_file_command): Call it.
4866 (symfile_open, symfile_init): New function.
4867 (add_file_target_command, add_file_addr_command): moved from
4870 * target.c (target_command): use target_kill.
4872 * target.h (target_files_info): Don't declare, never called
4875 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4876 files to determine stack end address.
4878 * valarith.c (value_x_binop, value_x_unop): Change error message
4879 to be more useful. Pass proper argument to value_struct_elt.
4881 * valops.c (value_assign): FIXME comment that long long
4882 bitfields will break here.
4884 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4885 Update `make saber_gdb' to work better.
4887 * TODO: A woman's work is never done.
4889 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4890 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4891 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4892 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4893 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4894 valops.c, valprint.c, exec.c: Lint.
4897 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4899 Continuing Intel 960 port merge of GDB.
4901 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4902 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4903 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4904 Wack over "make depend" so it handles files in subdirectories
4905 vx-share, nindy-share, bfd, and in the current directory.
4907 * blockframe.c (get_prev_frame_info): Remove fatal error
4908 if stack not defined.
4910 * core.c (core_open, core_detach): New functions that handle
4911 the old "core-file" command as "target core" and "detach" instead.
4912 (core_file_command): Call them.
4913 (core_xfer_memory): Use common routine xfer_memory.
4915 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4916 dbxread now uses bfd for everything but symbol reading itself.
4917 BFD internals are used to drag out the relevant file offsets.
4918 (partial_symbol_file_open): Change args all around for BFD.
4920 * symtab.c: Rename "value" to "val" everywhere, so we can
4922 (symbol_file_command): New command, moved from dbxread.c
4923 and coffread.c. It uses BFD to read the file, then vectors
4924 based on its type, to dbx or coff symbol readers.
4925 * symtab.h: Extern a few vars for symbol_file_command.
4927 * target.h: Breakpoint takes a char * save area, not a char **.
4929 * valprint.c (val_print): When unpacking bitfields, offset
4930 the address in gdb of the value, if it is declared with a shorter
4931 type. Remove the last "runtime kludge test" of host byte order.
4933 * utils.c: Remove old my_bfd_read routine.
4935 * stack.c (frame_info): Use target_has_stack. Print program counter
4936 register's actual name rather than "pc", since it's called the
4937 "ip" (instruction pointer) on the i960 (sigh).
4939 * target.c (target_command): Add command for selecting a target
4940 type and calling its open routine. This is used for initiating
4941 communication with a particular target, in a generic way.
4943 * tm-i960.h: Update for modern gdb. Remove semicolons from
4944 various macros. Handle reading struct return convention, and
4945 error-out attempts to return structs with the "return" command.
4946 Be sure gdb doesn't think we know how to call functions in the
4949 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4950 to i960_xxx in lower case.
4951 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4952 not being defined yet.
4954 * remote.c (remote_open): Call start_remote to initialize
4955 wait_for_inferior during open.
4956 (remote_xfer_inferior_memory): Return length written rather
4959 * remote-vx.c (target_command -> vx_open): Use new generic
4961 * remote-eb.c, inftarg.c, exec.c: ditto.
4963 * infrun.c: Fix comments.
4964 (attach_program -> child_open): Use new generic target command.
4965 (wait_for_inferior): Clear saved register values before target_wait,
4966 so target_wait can set some of them if convenient.
4968 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4969 Return success indicator, not void.
4970 (child_xfer_memory): Avoid fetching initial word if we'll
4971 overwrite it anyway.
4973 * infcmd.c (attach_command): Use new generic target open routine.
4974 (_initialize_infcmd): Update doc on attach and detach commands.
4975 (do_registers_info): Merge in a byte-order problem as a FIXME
4978 * findvar.c (find_saved_register): Avoid problem in current frame.
4979 (read_relative_register): Ditto.
4980 (write_register): Convert byte order on the way out.
4982 * exec.c (file_command): Add.
4983 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4984 (xfer_memory): Common function between core_xfer_memory and
4986 (exec_xfer_memory): Use it.
4988 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4990 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4991 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4992 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4994 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4996 Merge Intel 960 port of gdb, continuing...
4998 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4999 symbol_file_command): Pass from_tty arg to hush 'em up.
5001 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5002 Add magic numbers for 960 COFF format.
5004 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5006 Merge Intel 960 port of gdb, from Intel "1.2" release.
5008 CHANGE_LOG entries from their port, which was based on
5011 Thu Sep 6 11:02:22 PDT 1990
5012 Remove temp file if download is interrupted.
5014 Wed Aug 1 09:08:33 PDT 1990
5015 Now uses binary protocol to talk to NINDY.
5016 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5017 Times out after 5 seconds when trying to talk to NINDY.
5019 Tue May 29 12:54:49 PDT 1990
5020 Added variable baud rate (-b switch).
5021 Source code reorganization.
5023 Thu Apr 26 11:09:55 PDT 1990
5024 More cleanup of batch mode; specifically, execute "-s", "-e", and
5025 "-se" switches as soon as they are encountered on the invocation line.
5027 Fri Apr 20 13:47:15 PDT 1990
5030 Thu Apr 19 09:54:28 PDT 1990
5031 Add 'reset' command.
5033 Wed Apr 18 09:48:07 PDT 1990
5034 After opening remote tty, wait for 1 second to go by without input
5035 from it before trying to talk to NINDY (fixes problems with the
5036 Heurikon HK80/V960E).
5038 Mon Apr 4 16:33:05 PDT 1990
5039 Some output was not being suppressed in 'batch' mode.
5041 Thu Mar 22 15:31:11 PST 1990
5042 Ask user if old symbol table should be deleted when new file is
5045 Allow user to run a program downloaded before gdb960 was brought up.
5047 Correct "exec-file" help message for i80960 context.
5049 Correct bug in calculating user space address: could occasionally
5050 corrupt user program.
5052 Make sure to zero low-order bits in rip's because of bug in 960CA
5053 A-step part: could cause operation faults when "next"ing across
5056 Correct bug that made it impossible to get source line numbers for
5057 code loaded at addresses higher than 0x7fffffff.
5059 Wed Jan 10 12:43:22 PST 1990
5060 Open remote tty for exclusive use.
5062 Fri Jan 5 12:14:42 PST 1990
5063 Correct disassembly (CA manual was right after all):
5064 opcode for sysctl is 0x659
5066 Mon Oct 23 12:03:04 PDT 1989
5067 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5069 Mon Oct 16 14:15:09 PDT 1989
5070 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5072 Mon Oct 2 15:56:31 PDT 1989
5074 Added 960CA disassembly support.
5076 To simplify maintenance:
5077 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5079 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5080 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5081 - made disassembly interface identical to that in gdmp960.
5085 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5087 * target.h: Allow targets to stack. Add target_has_memory,
5088 _registers, etc. Restructure memory access and "info files"
5089 to walk the target stack.
5090 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5091 target.c: Change tables to match target.h.
5092 * inflow.c (child_mourn_inferior): pop child_ops.
5093 (generic_mourn_inferior): Use new has_stack flag.
5094 * infptrace.c (child_xfer_memory): New memory regime.
5095 * inftarg.c (child_files_info): New "info files" regime.
5096 * remote-eb.c: New memory regime, new info files.
5097 * remote-vx.c: New memory regime, new info files. Now use
5098 separate targets for VxWorks attachment to machine, and
5099 actually running a process under VxWorks, since one has
5100 stack & execution & regs and the other doesn't.
5101 * remote.c: New memory regime, new info files.
5102 * sparc-xdep.c (fetch_core-registers): New memory regime.
5103 * target.c: New routines and support for stacked targets,
5104 new memory regime, new info files regime.
5107 Generalize section handling for an arbitrary number of sections,
5108 including use of the new BFD (binary file) library.
5109 * gdbcore.h: Add struct section_table.
5110 * exec.c (build_section_table): Iterate all sections and
5111 record what gdb needs to know about them.
5112 (exec_command): Use it.
5113 (exec_xfer_memory): Use the table.
5114 (exec_files_info): Print the table.
5115 * core.c (core_file_command, core_xfer_memory, core_files_info):
5117 * source.c (find_source_lines): Use bfd_get_mtime.
5118 * dbxread.c: Quick changes to make it compile with new BFD.
5119 * utils.c (error): Avoid using bfd_error in generic routines.
5121 * core.c (core_fetch_registers): Get from the ".regs" section of
5123 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5125 * inferior.h (attach_flag): Export.
5126 * infcmd.c (run_command): use new target_create_inferior.
5127 * infrun.c (child_create_inferior): Don't return result.
5128 * Makefile.dist (VERSION): 3.91.4.
5130 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5132 * breakpoint.c (bpstat_num): Handle breakpoints which have
5133 since been deleted, such as temporary breakpoints.
5134 infcmd.c (program_info): ditto.
5136 * core.c (core_file_command): Display the frame where the core
5141 * remote-vx.c (target_command): Merge in target command from
5142 targ-vx.c. A few other cleanups.
5144 * TODO, Projects: Lots more stuff to do...
5146 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5148 Massive changes to wall off the remote-debugging interface
5149 behind a function vector. The port to handle VxWorks targets
5150 is also part of this.
5152 All files: Replace references to renamed functions,
5153 remove references to remote_debugging, remove references to
5154 have_include_file, have_core_file in favor of target_has_stack,
5155 target_has_memory, etc.
5157 * Modularize the breakpoint interface.
5158 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5159 a breakpoint instruction.
5160 breakpoint.c: struct breakpoint's shadow_contents now sized as
5162 (insert_breakpoints): Vector to target to install breakpoints.
5163 (remove_breakpoints): Vector to target here too.
5164 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5165 sparc-tdep.c (single_step): Use new breakpoint interface for
5166 the single-step breakpoints.
5167 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5168 New file, contains routines to insert and remove breakpoints by
5169 reading out the old contents and later replacing them. This is
5170 how ptrace breakpoints work, and many remote systems as well.
5172 * tm-vxworks68.h: New config file, overrides a few things for
5173 Wind River's preferences.
5175 * target.h: New file, for transfer vector used to talk to the
5176 inferior (child, attached, core, exec, remote, etc). All accesses
5177 to the thing being debugged should come through these vectors.
5178 target.c: New file, routines to handle transfer vector.
5179 (various files): Add transfer vectors XXX_ops for the various
5180 targets and pseudo-targets (core files, etc) we support.
5182 * breakpoint.c (bpstat_stop_status): Further explorations of
5183 watchpoints and why things don't work all the time.
5184 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5186 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5187 the local gdbinit if it doesn't already have it.
5189 * core.c (core_ops): add and install.
5190 Allow core debugging without exec file.
5192 * dbxread.c (free_and_init_header_files): Merge two fns.
5193 (end_symtab): Free named symbol table when a new version comes in.
5194 (read_dbx_symtab): Relocate all kinds of symbols with base
5195 address. First step toward handling different text, data, bss
5197 (add_file_addr_command): Renamed add_file_command.
5198 (add_file_command): Vector to remote handler.
5199 Add "load" as an alias for "add-file" command.
5201 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5202 non-returning functions.
5204 * exec.c: Add exec_ops, and push it as a target when an exec
5207 * infcmd.c (run_command): Pass executable file name and arg list
5208 separately when starting an inferior. Permit "run" when no exec
5209 file is specified, for VxWorks.
5210 (detach_command): Move to child_detach in inftarg.c.
5212 * inftarg.c: New file. Unix-child-specific routines, and the
5213 child_ops structure.
5215 * inferior.h (registers): Export "registers" as the way for
5216 target dependent register handlers to find gdb's local copy of
5217 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5218 since it is now used by places that want wait_for_inferior to
5219 handle the grunge but want to see every trap from the inferior.
5221 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5222 Eliminate remote_debugging hooks in terminal handling.
5224 * infrun.c: Replace start_inferior with child_create_inferior.
5225 Move all the hair of Unix shells and ptrace idiosyncracies into
5226 child_create_inferior, so remote handlers don't have to deal.
5227 Remove running_in_shell. Rename stop_after_attach to
5228 stop_soon_quietly, and use it in a few other places where we want
5229 to just call wait_for_inferior and get control back on the first
5230 trap. trap_expected now never takes a value > 1.
5231 (init_wait_for_inferior): Initialize static vars when a new
5234 main.c (gdbinit): Add new hook for .gdbinit file name, let
5235 it be overridden by config files as GDBINIT_FILENAME.
5236 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5237 Both of these are used for VxWorks gdb.
5239 mcheck.c: rename include file "gmalloc.c" to avoid problems
5240 with system include file "malloc.c".
5242 param-no-tm.h: New include file, same as param.h but does not
5243 include the default "tm.h" file. This is used in files where
5244 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5246 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5248 remote-vx.c: New file, VxWorks remote debugging support. Uses
5249 RPC routines that are shared with the target system, in directory
5252 remote.c: Vectorize remote interface.
5254 source.c: Globalize source_path, and make an alias "l" for "list"
5255 since we now have the "load" command.
5257 sparc-xdep.c: Use new param-no-tm.h.
5259 symmisc.c (free_named_symtab): Add new function from Wind River.
5260 However, ifdef it out for now while we think about what it should
5263 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5265 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5266 non-Unix-children handle this with their own code in the target
5269 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5270 source and target lists. Add vx-share to default list of include
5271 directories. Add new files to src and target lists: mem-break,
5272 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5273 ${srcdir} versions of munch and createtags are used.
5275 * valops.c (find_function_addr): Split out of call_function.
5276 (call_function_by_hand): Rename call_function; this function
5277 calls functions in the target by laboriously patching the target
5278 word-by-word with the right stack, args, regs, etc.
5281 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5283 Handle AMD 29000 a bit better.
5285 * remote-eb.c (readchar): Mask received char log to make it readable.
5286 (remote_start): Pass arguments down to executing program.
5287 Make startaddr unsigned.
5288 infrun.c (start_inferior): Accept args, pass them to
5290 infcmd.c (run_command): Pass args down to start_inferior.
5292 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5293 the target object file format.
5294 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5296 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5297 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5299 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5301 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5302 * TODO: We did a few things, we have more to do though.
5304 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5305 * inflow.c (inferior_died): Clear deferred stores.
5307 * Debug problems with dummy frames and calls to the inferior.

5310 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5311 (sparc_push_dummy_frame): Simplify and fix what we push.
5312 (sparc_pop_frame): Slightly more hair here, deciding whether
5313 we are restoring a saved PC or returning to a return address in %i7.
5314 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5316 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5317 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5318 * obstack.h (chunkfun): ditto.
5319 * defs.h (xmalloc, xrealloc): ditto
5321 * utils.c (quit): Grab the terminal from the child if necessary.
5323 * inflow.c (term_status_command): Rename to term_info, change
5326 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5327 (is_delayed_branch): Speed up.
5328 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5329 Still missing some float ops, and needs testing.
5331 * Support for input and output radixes other than base 10
5332 * defs.h (input_radix, output_radix): Declare.
5333 * expread.y (yyparse, parse_number): Handle changes of input
5334 radix, and ambiguous names-or-numbers in radixes >10.
5335 * printcmd.c (print_scalar_formatted): Print formatted hex
5336 numbers in varying column widths.
5337 * valprint.c (val_print): Use output_format to print scalar ints.
5338 (set_input_radix, set_output_radix, set_radix): Create.
5339 (set_output_radix): Set output_format from output_radix.
5340 (_initialize_valprint): add `set radix' but leave the others off.
5342 * main.c (execute_command): Let stupid questions be turned off.
5343 (_initialize_main): Handle "set stupidity", etc.
5345 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5346 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5348 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5350 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5351 bfd stuff is still screwed up, but with some manual work, it
5354 * breakpoint.c (bpstat_do_actions): Start over if a command
5355 proceeds the inferior, since the inferior will have stopped and
5356 will need to have its new stop-actions taken care of.
5358 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5359 compiler fits, simplify it.
5361 * gdb.texinfo (directory command): Doc new dir command.
5362 source.c (directory_command): "dir" now puts things on the front
5363 of the path, moves dups up front, and handles multiple names
5364 on the command line, inserting each one in order. It also
5365 blows away cached line and full_filename info.
5367 * stack.c (backtrace_command): Skip "more stack frames follow"
5370 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5371 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5372 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5373 The only odd one was Gould NP1, which had defined vprintf to
5376 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5377 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5378 variable, inspect_it.
5379 valprint.c (print_string, val_print): Use the global inspect_it
5380 to indicate whether to print in Epoch style or normal style.
5382 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5384 * printcmd.c (call_command): add an alias for the "print" command
5385 which runs expressions and doesn't print the result if void.
5386 (print_command_1): implement it.
5388 * command.c: Remove #if 0'd code. Initialize all the fields
5389 in add_cmd (). Rename do_nothing_command to
5390 not_just_help_class_command, and make it externally visible.
5391 command.h: add user_commands to struct.
5392 * main.c (define_command): Don't overload c->function with a char
5393 string as well as a function pointer.
5395 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5396 calling convention of value_struct_elt () that got dropped in
5399 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5400 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5402 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5404 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5405 until a good time (e.g. when we are about to run the child),
5406 saving ptrace calls.
5407 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5408 * tm-sparc.h: define DO_DEFERRED_STORES.
5410 * sparc-xdep.c (store_inferior_registers): when storing float
5411 registers, don't store stack regs too. When storing the SP,
5412 however, DO store the stack regs too. This fixes a bug in which
5413 the dummy frame is not recognized when a call_function finishes,
5414 because its frame pointer (in the stack regs) was never
5416 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5417 even though we don't know how to read them from an inferior.
5418 valops.c (call_function): Comment about storing SP.
5420 * infrun.c (save_inferior_status): Save away the original bpstat
5421 chain so it can be restored later. Install the copied version for
5422 use by whoever saved the status. It will be blow away by
5423 restore_inferior_status, and the original chain restored. This is
5424 important for people who have pointers into the original.
5426 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5427 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5428 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5431 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5433 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5434 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5435 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5437 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5439 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5440 Store the baseclasses in a type struct starting from array element
5441 0 rather than from the unusual array element 1.
5443 dbxread.c: the above.
5444 (virtual_context): Add
5445 Read new debug information about which virtual function table
5446 a virtual function is from, and store it in fn_field.fcontext.
5448 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5449 TYPE_FN_FIELD_STATIC_P.
5451 symtab.c: the above.
5452 valops.c: the above. Handle pointer casts of object *'s.
5453 (search_struct_method): Add.
5454 (value_struct_elt): First arg is now a pointer to a value, and is
5457 valprint.c: the above.
5458 values.c (value_virtual_fn_field): Add type arg. Handle
5459 offsetting to the proper object when calling virtual fns.
5461 (baseclass_addr): Add valuep arg.
5463 * README: Document the current state of BFD config (missing).
5464 * TODO, ChangeLog, Makefile.dist: Roll version.
5465 * WHATS.NEW: Add summary of changes since 3.5.
5467 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5469 * dbxread.c (read_struct_type): Clear bit vectors whenever
5471 symtab.c (B_CLRALL): define.
5473 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5474 using == rather than =. Huh... This fixes the dreaded problem
5475 wherein builtin_type_int becomes TYPE_CODE_FLT.
5477 * core.c (info_files): Show the inferior pid.
5479 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5480 already knows how to look in the source directory.
5482 * Remove psymtab hair from many places. Remove duplicated code
5483 for searching symbol tables. Hide psymtabs from most places.
5484 Make it fast to get from a psymtab to its symtab.
5486 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5487 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5488 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5489 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5490 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5491 new symtab completely. New psymtabs get symtab pointer
5492 initialized to zero. Remove MI warning printf.
5493 symtab.h: Comments. Add psymtab to symtab pointer.
5494 (PSYMTAB_TO_SYMTAB): New macro.
5495 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5496 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5498 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5500 (print_frame_info): Avoid special-casing symbols that have not yet
5503 * source.c (open_source_file): Quick path if we have already
5504 located the source file by its full name.
5506 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5507 find_pc_psymtab. When a name is found in the misc function
5508 vector, search the symbol table for its mangled name, not the
5509 name that the user typed.
5511 * bfd.h: Fix missing comment terminators, make #endifs match.
5513 * valarith.c (value_less): Handle unsigned int comparisons.
5514 Add FIXME about pointer compares, which assume host and target
5515 pointers are the same.
5517 * command.c (do_nothing_command): lint
5518 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5519 fix comments on debug symbol format for visibility. Actually set
5520 visibility of symbols.
5521 main.c (echo_command): lint; use <readline/history.h>.
5522 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5523 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5524 pointing past end of allocated memory; saber complains.
5525 obstack.h: Declare the external functions that we use.
5526 valarith.h: use <string.h>
5527 solib.c (solib_add): lint.
5529 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5531 * main.c (initialize_main): Default info_verbose to off, now that
5532 symbol reading is fast.
5533 (quit_command): Avoid clobbering exec_bfd while quitting.
5535 * Initial BFD (binary file diddling library) merger:
5536 coffread.c: Change AOUTHDR to struct exe_hdr.
5538 core.c: initialize initialized data at compile time.
5539 (core_file_command): Move from coredep.c, convert to bfd.
5540 (xfer_core_file): Convert to bfd.
5541 exec.c (exec_file_command): use bfd routines.
5543 mips-tdep.c: Remove exec_file_command and friends.
5546 * coredep.c: (fetch_core_registers) Convert core_file_command to
5547 fetch_core_registers.
5548 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5550 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5551 (my_bfd_read): More bogosity, which I don't think we call.
5552 (program_name): Remove this atrocity asap!
5554 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5557 values.c: allocate_repeat_value was not clearing the
5558 optimized_out field.
5559 (value_static_field): minor stylistic fix (wrong macro was used).
5560 valops.c (value_struct_elt_for_address): didn't work for C++
5563 * signame.c (_initialize_signame): Initialize signal names once.
5565 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5566 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5567 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5569 * remote-eb.c: Support user-settable baud rates on the serial port.
5571 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
5573 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
5575 * tconfig/sun3os4: Remove warning about native assembler,
5576 since it also occurs in the xconfig file.
5578 * findvar.c (registers): Allocate some slop after `registers'
5579 to prevent stray accesses from trashing the next variable.
5581 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
5582 on the sun-3, by changing the #ifdef from `sun3' (which is not
5583 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
5584 vars, which happened to follow `registers' in the executable.
5586 * readline/history.c (history_search): Heed gcc-2's advice
5587 and parenthesize && inside ||).
5589 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
5590 tm-29k.c: Insert FSF copyright headers.
5592 * remote-eb.c: Better comments.
5594 * Makefile.dist: Update to 3.91.6.
5595 * TODO: note PREPARE_TO_STORE problem.
5597 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
5599 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
5601 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
5603 * infrun.c (wait_for_inferior, at end): Don't set up
5604 prev_* if the inferior no longer exists.
5606 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
5607 CANNOT_EXECUTE_STACK.
5608 valops.c (call_function): Use it.
5610 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
5612 * inferior.h (PC_IN_CALL_DUMMY): New macro.
5613 infrun.c (wait_for_inferior, 2 places): Use it.
5615 * values.c (value_being_returned): Only use
5616 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
5618 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
5619 right thing for remote-eb.c.
5621 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
5622 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
5624 * blockframe.c: Put get_frame_saved_regs inside #if !defined
5625 (FRAME_FIND_SAVED_REGS).
5627 * findvar.c ({fetch,store}_registers): Check for
5628 REMOTE_{FETCH_STORE}_REGISTER macro.
5630 * findvar.c (get_saved_register): Add argument lval and
5631 change meaning of argument addr.
5632 findvar.c: Change calls to get_saved_register to reflect
5633 new calling convention.
5634 valops.c (value_assign): Use get_saved_register instead of
5635 find_saved_register.
5637 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5639 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
5640 an (uninitialized) pointer to one. Use "&" when passing it
5643 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
5645 * coffread.c (getfilename): Use DGUX x_offset and x_name if
5648 * coffread.c (symbol_file_command): Put semicolon after
5650 Put safe_to_init_tdesc_context in #if defined (TDESC).
5651 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
5652 coffread.c: #include <sys/stat.h>.
5653 (read_coff_symtab): Typo: in_source_files -> in_source_file.
5654 Add missing ')' in check for "lc%" and friends. Remove
5656 Declare read_one_sym() at top of file.
5657 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
5658 MC68WRMAGIC can have the same value without causing a duplicate
5661 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
5663 * Allow a Makefile to be built without building the
5664 tm and xm file links that screw up builds in subdirectories.
5665 This is done with `config.gdb none', then you can do things
5666 like `make gdb.tar.Z'.
5667 * tconfig/none: Config file for no target system
5668 * xconfig/none: Config file for no host system
5669 * config.gdb: If no TM or XM files are called out by the
5670 host or target file, don't make links for them.
5672 * cplus-dem.c: Add documentation.
5674 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
5675 simple error, so the user's gdb doesn't crash due to some object
5676 file problem (e.g. somebody is rebuilding the file out from under
5679 * printcmd.c (print_address_symbolic): demangle the symbol.
5681 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
5682 Motorola copyrights in it. Make "make gdb.tar.Z" work.
5683 (alldeps.mak): sort and uniq all results from this; duplicates
5684 hose gdb.tar.Z link building. Remove RCS files from
5685 tconfig and xconfig. Add config files for sun386. Add
5686 a few odd files to OTHERS and HFILES.
5688 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
5690 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
5691 Roll version number to 3.91.5. Make lint work in bindir.
5693 * README: Document cross-debugging and new file structure.
5695 * blockframe.c: Lint. Include "value.h" to declare read_register.
5696 (find_pc_partial_function): remove duplicate line.
5698 * command.h: Lint. Declare error_no_arg and dont_repeat.
5700 * tm-news.h: Remove inadvertently duplicated stuff.
5702 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
5703 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
5705 * config.gdb: Allow `config.gdb host target' form. Clean
5706 up previous change that printed bogus messages when you just said
5709 * core.c: #include "command.h" for lint.
5712 * main.c: Remove some casts of enums. Lint.
5719 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
5721 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
5722 read it from memory. This will allow us to save ptrace calls
5723 eventually. Changed caller single_step too.
5725 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
5726 that we aren't going to use, saving many ptrace calls, especially
5727 when watchpointing or single stepping. Use some #define's for
5729 (store_inferior_registers): Ditto.
5730 (core_file_command): Use some #define's for constants.
5732 * tm-sparc.h: Add #define's for some register numbers, so we
5733 can eliminate the use of random constants in sparc-xdep.c.
5735 * stack.c (frame_command, print_frame_info, up_command,
5736 down_command) Remove frame_changed, since it
5737 causes a bug and doesn't seem to do anything useful. In some
5738 places it was used as a flag, in others as a stack level (?).
5740 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
5741 default is to use the portable (vprintf) version rather than the
5743 * xm-news.h (MISSING_VPRINTF): Add.
5745 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
5747 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
5749 * Remove stuff that forces -Bstatic linking of gdb, and warnings
5750 about linking debugged programs -Bstatic in the sun?os4 config
5751 files in tconfig and xconfig subdirectories.
5753 * main.c (main): Remove unreached exit(0) now that we exit
5756 * Create TODO file for online bug list. There are too many
5757 "little" bugs to keep track of on paper.
5759 * Change Projects file to refer to bug-gdb@cygnus.com
5760 rather than kingdon@ai.
5762 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5764 * Makefile.dist (VERSION): 3.91.4 now.
5766 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5767 (condense_misc_bunches): Add sanity check that misc_count is
5768 the same as the number of symbols in the bunch.
5770 * coffread.c: rename init_misc_bunches. Pass an argument
5771 to condense_misc_bunches (a zero).
5773 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5774 every time we are called; don't rely on our caller to do it.
5775 (add_file): Remove call to init_misc_bunches.
5777 * mipsread.c: Only warn, don't error, if unknown symbol types.
5778 This keeps an old gdb from falling on its face if it sees newly
5779 extended symbol info. Rename init_misc_bunches.
5781 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5783 * Merge in changes from Per Bothner for DECstations and other
5784 MIPS stuff. The rest is Bothner speaking:
5786 The next message is a merger of Alessando Forin's mips port with
5787 mine. I've tried to use my good if biased judgment to get
5788 the best of both. It *does* need testing.
5790 Some of the changes are general, *not* mips-specific.
5793 Didn't believe in little-endian bit order.
5794 There are still inconsistencies about whether flags
5795 like BITS_BIG_ENDIAN are integer (#if ...) or
5796 boolean (#ifdef ...). I tried to paper over them.
5798 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5799 Moved some misc_function code that was common to
5800 {dbx,coff,mips}read.c to symtab.c.
5801 In the process, I think I cleaned things up a bit.
5802 At the same time, moved obsavestring and obconcat to symtab.c.
5805 Removed obsolete condense_addl_misc_bunches (use
5806 condense_misc_bunches(1) instead).
5809 Needed to include <sys/dir>, at least on DECstations.
5811 valops.c, mips-tdep.c, tm-mips.h:
5812 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5813 conventions (when STACK_ALIGN is insufficient).
5814 Needed on mips, where doubles need 8-byte alignment,
5815 but ints only need 4.
5818 Removed cruft that was not being used.
5819 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5822 Print $ before register-names (I think that makes things a little
5824 Never print two instructions, even if one delays.
5825 Removed hex-disassemble set_cmd. (This is not mips-specific,
5826 so I think the argument is whether it is generally worthwhile or not.
5827 I'm inclined to think not, given how easy it is to
5828 convert between radixes in gdb.)
5831 This is basically Alessando's code.
5832 It doesn't use obstacks; I changed it to use obstacks
5833 in a few minor places where using malloc causes a
5834 memory leak. (Probably, more places could/should be changed.)
5835 I added record_misc_function where it was missing.
5836 In symbol_file_command and add_file_command, I tried
5837 to make the code consistent with more recent versions.
5838 Minor sylistic changes in parse_procedure.
5839 Make a .gdbinfo. psuedo-symbol point back to the real
5840 procedure symbol (using the isym field).
5843 This is basically from my port, but with a lot of details
5844 and a number of routines merged in from Alessando's version.
5845 I basically used my code "raw" backtrace (use heuristics
5846 from the actual code, rather than symbol table info) - though
5847 the idea is Alessandro's. I feel my code is a little cleaner
5848 here, particularly in being a little more flexible, such as being
5849 able to handle gcc-produced code (which it now can).
5850 It also doesn't do frame caching (which is not useful
5851 more recent gdb versions).
5852 I also used my code for push_/pop_dummy, more or less.
5853 I tried to incorporate AF's code for testing sigtramp
5854 while backtracing; I probably got it wrong.
5855 Added mips_print_register, which tries to scrunch as much
5856 information as possible on a screen...
5857 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5858 under mips-pinsn.c), I don't see anything mips-specific here,
5859 and I don't see it being all that useful anyway.
5862 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5863 Use more register names (rather than hard-cases numbers).
5865 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5867 * Hack up 3.90.11 changes:
5869 * Makefile.dist (depend): parameterize $(GCC).
5870 Add solib.c and solib.o.
5871 (readline): Fix vpath for both absolute or relative SRCDIR.
5873 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5874 Also, let the part I didn't understand at least compile so
5875 I can test the rest. FIXME.
5877 * dbxread.c: Fix thinko using strcmp.
5878 (init_psymbol_list): declare static.
5879 (partial_symbol_file_open): Comment cleanups better, avoid
5880 cleaning up the string table since the caller will do that.
5881 Move the stat for mod time into symbol_file_command, temporarily.
5882 (There should be a mod time for each symbol file, eventually,
5883 to control its rereading. FIXME.)
5885 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5886 SunOS, which gives error for shared libs otherwise. (From
5887 Schaefer, probably FIXME needs work for portability.)
5889 * solib.c: Move #include "param.h" to work.
5890 Lowercase all the Uppercase Letters In the Messages.
5891 (find_solib): Clean up inferior_so_name for debug printouts.
5892 Allow no argument, to mean all shared libraries.
5894 * symmisc.c: include param.h to get CLEAR_SOLIB.
5896 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5898 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9

5907 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5911 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5913 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

5917 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5919 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5920 Put parens around gcc_p in expansion.
5922 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5924 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5926 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5928 * Changes for Sun shared libraries:
5929 blockframe.c (find_pc_partial_function): If a non-text symbol
5930 is found, set *address = pc - FUNCTION_START_OFFSET.
5931 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5932 Disable breakpoints instead of giving an error.
5933 source.c (select_source_symtab): Initialize cs_pst.
5934 symmisc.c: Call CLEAR_SOLIB if defined.
5935 symtab.h: Make text{low,high} CORE_ADDR not int.
5936 (psymtab): New field addr.
5938 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5939 (record_misc_function): Give correct type for N_DATA symbols.
5940 (condense_misc_bunches): do "misc_function_count = j" regardless
5942 Take code which is shared between symbol_file_command and
5943 add_file_command and put it into partial_symbol_file_{open,read}.
5944 Split add_file_command into add_file_command and add_file.
5945 Make psymtab_to_symtab read in the string table if the file
5947 Two new parameters to read_dbx_symtab and start_psymtab.
5948 tm-sunos.h: New file.
5950 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5952 * infcmd.c: Change cont_command to continue_command and "cont"
5955 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5957 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5959 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5961 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5962 size 1,2,4,8 rather than size < 8.
5964 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5965 as necessary, not just once.
5967 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5969 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5971 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5973 * tm-news.h: Add CALL_DUMMY_*.
5975 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5977 * config.gdb: In list_host, list_target, use ${i}, not $i.
5979 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5981 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5983 * sparc-opcode.h: Change all store floating-point state register
5984 instructions to have the right match & lose fields.
5986 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5988 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5990 config.gdb: If srcdir != ., create readline directory and
5991 copy a makefile into it.
5993 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5994 consistency with POSIX.
5996 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5997 when we exit its exp_valid_block.
5999 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6001 * Makefile.dist: Bump version to 3.91.3.
6003 * Clean up handling of breakpoint commands (somewhat).
6004 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6006 inferior.h: Add breakpoint_proceeded to inferior status struct
6007 and globals; save it and restore it.
6008 (clear_breakpoint_commands): Cleanup, remove old #define.
6010 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6011 (save_inferior_status, restore_inferior_status): handle it also.
6012 (proceed): Remove earlier code that set breakpoint_proceeded.
6013 It is now set only in clear_proceed_status.
6014 (clear_proceed_status): Cleanup, use bpstat_clear rather
6015 than clear_breakpoint_commands. No callers need the stop_bpstat
6016 between clear_proceed_status and proceed.
6018 infcmd.c: Add breakpoint_proceeded definition and comment.
6019 (cont_command, jump_command, signal_command): Move call to
6020 clear_proceed_status right next to call to proceed.
6022 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6023 caller's argument while running down the chain of breakpoints.
6024 Use new variable "breakpoint_proceeded" to determine when
6025 a command that it executes moves the inferior past the
6027 (bpstat_clear): Handle NULL argument.
6028 (bpstat_clear_actions): Avoid useless call to
6029 breakpoint_auto_delete.
6030 (delete_breakpoint): Clean up bpstat's that are pointing to
6031 the deleted breakpoint from the stop_bpstat chain.
6032 (breakpoint_auto_delete): Simplify.
6034 * Clean up handling of EOF, error on stdin, etc. This was
6035 prompted by a network problem that caused gdb to go into an
6036 infinite loop filling up its malloc'd memory.
6038 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6039 not clear_breakpoints_commands, which is now gone.
6040 (main): If command_loop returns (e.g. from EOF on stdin), do
6041 a quit_command (looping back to command_loop if quit_command
6042 doesn't really quit).
6043 (command_loop): check result from command_line_input and
6044 exit if it returns NULL, rather than passing the NULL to
6046 (gdb_readline): Free malloc'd result space before returning
6049 * utils.c (query): Handle C-d to mean "yes", just as if the
6050 input was not a terminal. Also avoid infinite loop if EOF
6051 occurs in mid-input-line before newline. This allows
6052 query to be used at EOF on stdin with reasonable results.
6054 * infrun.c (proceed): Set breakpoint_proceeded.
6056 * values.c (value_as_long): Avoid infinite recursion for enums.
6057 (_initialize_values): Fix typo in help msg (kingdon).
6059 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6060 RL_LIB for linking. This allows -lreadline for linking
6061 and nothing for dependencies, once readline is a real library.
6063 * config.gdb: Jim Kingdon: give useful error message if the
6064 host or target type is not recognized.
6066 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6067 it just defines it. Dumb, but deal with it.
6069 * Jim Kingdon suggests:
6070 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6072 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6074 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6076 * Clean up Bothner's changes.
6078 * blockframe.c (clear_pc_function_cache): New function.
6079 * blockframe.c: remake cache_pc_function_* static.
6080 * dbxread.c (symbol_file_command): remove references to
6081 cache_pc_function_* variables.
6082 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6083 * printcmd.c: Avoid kludging a global variable (addressprint)
6084 to avoid printing the address of a string twice. Instead,
6085 pass the format letter 's' down low enough that it can be seen
6086 to avoid this problem.
6087 (print_formatted): Pass format arg to value_print.
6088 (restore_addressprint): Remove function.
6089 (do_examine): Avoid hacking addressprint, cleanups and such.
6090 (print_frame_args): Add a comment to a Bothner change.
6091 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6092 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6093 to wipe out the values cached in blockframe.c.
6094 * symtab.c (find_method): Add comment saying how big you must
6095 allocate to be "big enough". Per being terse again.
6096 * valprint.c (val_print): Handle format letter "s" to print
6097 strings without addresses. Add comment to vtbl printing code
6098 which casts with wild abandon. Rearrange reference-printing
6100 @0xaddr: value (print w/addressprint)
6101 value (print w/~addressprint)
6102 @0xaddr (parameter lists w/addressprint)
6103 or nothing (parameter lists w/o addressprint)
6105 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6107 * Merge more changes from Per Bothner:
6109 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6110 annoying) that I tried to improve it. Here are my suggestions.
6112 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6115 Do automatic de-reference when taking the address of a reference.
6117 Don't deref_ref when printing parameter lists.
6119 More attempts at treating refernences properly.
6121 In val_print, if deref_ref==0, don't print dangling " = ".
6123 Add COERCE_REF macro, which de-references an REF.
6125 * Merge changes from Per Bothner:
6127 * Fixed (Sony news)-specific configuration problems.
6128 * Fixed other problems with using vanilla pcc and libc (enum problems;
6129 assumption that vsprintf exists).
6130 * Some major speed-ups (finc_pc_partial_function now caches a match;
6131 parsing avoids duplicate symbol_lookup calls).
6132 * Changed handling of baseclasses (no longer use baseclasses field
6133 of struct type, use the first n_baseclasses fields instead).
6134 * Various minor changes/fixes, most C++-related.
6137 Cache the most previous match from find_pc_partial_function.
6138 (Save both low and high ends of matching function's pc range.)
6139 This speeds up the loop of infrun.c:wait_for_inferior quite
6140 a bit, and makes step/next commands much zippier.
6142 Added an enum->int cast (otherwise, some compilers barf).
6144 No longer set baseclass offset to 0, since multiple
6145 inheritance now mostly works.
6146 Added a number of casts, to shut up compiler warnings
6147 (after stabs where made enums, not ints).
6148 When discarding a symbol table (in symbol_file_command),
6149 must clear the cache introduced in blockframe.c.
6150 Don't convert $vtbl_ptr_type to vtbl any more.
6151 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6152 Mask off sign bit emitted by g++ for virtual table offset.
6153 Set voffset to -1 (not 1) for static member functions.
6155 Changed parsing/lexing of names to avoid doing symbol lookup twice
6156 (once when lexing to determine symbol class, once for real).
6157 Now only call symbol_lookup once. Fields of 'this' win especially big.
6159 Subpress printing addr twice in the case of 'x/s addr'.
6161 lookup_basetype_type is no longer used.
6162 Add find_methods as recursive helper function to decode_line_1.
6163 This allows multiple inheritance to work.
6164 Also, once one or more matches has been found, do not look in
6165 base-classes. (Baseclass methods would be overridden, anyway.)
6167 Removed baseclasses array in struct type.
6168 Instead of using baseclasses[i], use fields[i-1].
6169 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6170 Changed sign convention of voffset (previous was inconsistent).
6172 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6174 Used to assume existence of vsprintf. Re-written to not need it
6175 if HAVE_VPRINTF is undefined.
6177 typecmp was too pessimistic. Made it less so.
6179 Don't print space after address.
6180 If vtable points to a misc symbol (with 0 offset), print it,
6181 since that indicates the actual class of the object.
6182 Changed ype_print_derivation_info to use new inheritance
6183 scheme (without baseclasses vector).
6185 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6186 Also, changes needed because TYPE_BASECLASSES were removed.
6188 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6190 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6193 If there is no path set, and the symbols don't indicate what directory
6194 a file was compiled in, look in the current directory. But either
6195 a path or a known compilation directory will prevent this.
6198 Three independent bug fixes:
6199 * Remove the #if 0 block that breaks some stuff.
6200 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6201 adapt gdb to either SunOS 4.0.* or 4.1.
6202 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6205 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6208 (type_print) Demangle the name being printed.
6209 (type_print_base) Handle botched demangling without coredump (tiemann).
6212 (check_stub_method): Document routine.
6213 (tiemann) fix bug for no-arg functions
6214 Avoid clobbering beyond end of malloc'd storage.
6215 Terminate the argument list properly.
6217 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6219 * Changes merged by John Gilmore:
6222 In breakpoint_1, use new print_address_symbolic instead
6223 of find_pc_partial_function. (This forces use of assembler-level
6224 addresses, and avoids misleading non-mangled source-level names.)
6226 Generalize ansi argument such that -1 means skip arglist totally.
6227 Removed global variable print_ansi_qualifiers (which made
6228 code non-reentrant), in favor of extra explicit arguments
6229 to internal routines.
6231 Add new helper function print_address_symbolic.
6232 Use find_pc_misc_function instead of find_pc_partial_function
6233 (since we want assembler-level symbols here).
6235 Print unknown function as just "f (...)", not "f (...) (...)".
6236 Use new fputs_demangled explicitly.
6238 Fixed a typing violation (problem: value.h cannot be imported
6239 without renaming many variable in this file).
6240 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6241 decode_line_1: Moved forward some never-reached code.
6242 Made decode_line_2 skip function prologues correctly.
6244 fputs_filtered should not demangle by default.
6245 Add new fputs_demangled to demangle on demand..
6247 Change value_struct_elt to use value_primitive_field (using recursive
6248 utility function search_struct_field). This allows foo.bar to work
6249 for multiple inheritance (so far only for data fields).
6250 Change check_field in the same way (recursive helper function
6251 to support multiple inheritance).
6252 (Note: there are more of these problems that I haven't fixed.
6253 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6254 value_of_this: 'this' symbol name is now just "this", note "$this".
6256 Don't print static members.
6257 Avoid printing "members of <type>" if there are none.
6258 Simplified type_print_derivation_info by merging duplicate code.
6259 Remove useless blank lines in type_print_base (ptype command).
6261 Added declaration of new routine value_primitive_field.
6263 Added value_primitive_field which is generalized version of
6264 value_field that can handle multiple inheritance (non-zero offsets etc).
6265 Re-implemented value_field to call value_primitive_field.
6267 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6269 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6270 delete the whole environment. Karl Berry reported the bug.
6271 * source.c - fix openp to avoid //'s in filenames, which
6272 trigger an Emacs bug causing it to not be able to find files
6273 when running gdb in a window.
6274 * dbxread.c - zap the #if 0 that botches the add-file code.
6275 It seems to work a lot better without all the code commented out.
6277 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6279 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6282 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6284 * Makefile - added a ${CFLAGS} to a couple of entries,
6285 added remote-sa.sparc.c
6286 * added remote.sa-sparc.c, a modification of remote.c
6287 which conducts a dialog directly with the SparcStation prom.
6288 * breakpoint.c, infrun.c, sparcdep.c added
6289 remote_insert_breakpoint(), and remote_remove_breakpoint()
6290 to breakpoint.c instead of directly writing breakpoint instructions.
6291 * sparcdep.c on remote_debugging,there is no need
6292 to remove signle step breakpoint instructions.
6293 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6295 * printcmd.c - epoch interface sends lisp expressions to open up
6296 epoch windows on inspection.
6297 * valprint.c - added arrayprint, and addressprint and made adding
6298 format controls easier
6299 * wait.h added a couple of undef's because we were getting
6300 complaints about WSTOPSIG and WTERMSIG begin redefined.
6303 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6305 * symtab.c (decode_line_1): Add support for handling method stubs
6306 in the type information.
6308 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6310 * values.c (baseclass_addr): Run loop from INDEX+1 to
6311 N_BASECLASSES; otherwise, we can still get into a loop.
6312 @@ This should be restructured to use a cleaner search strategy.
6314 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6316 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6317 abbreviation "Tt" for tags which have the same name as their
6320 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6322 * symtab.c (list_symbols): add ability to set breakpoints on all
6323 the functions which match a particular regular expression.
6325 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6327 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6328 should print ANSI qualifiers (such as `const' and `volatile').
6329 All callers changed to call with ANSI == 1, except from
6330 `check_method_stub', which uses old-style syntax.
6332 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6333 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6335 * values.c (check_stub_method): New function.
6337 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6339 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6340 * valprint (type_print_base): Ditto.
6342 * symtab.c (gdb_mangle_typename): New function.
6344 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6346 * breakpoint.c (catch_command): New function. Provides a
6347 mechanism to set breakpoints based on catch clauses.
6348 (disable_catch): Similar, but disables breakpoints on catch
6350 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6352 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6354 * blockframe.c (blockvector_for_pc): New function.
6355 * blockframe.c (block_for_pc): Changed to call
6356 `blockvector_for_pc' and get the block itself.
6358 * stack.c (catch_info): New function. Prints info about
6359 exceptions which can be caught in the current frame.
6360 * stack.c (print_frame_label_vars): New function. Similar to
6361 `print_frame_local_vars'.
6362 * stack.c (print_block_frame_labels): Prints out labels that are
6363 defined in this frame. These labels are exceptions that can be
6366 * dbxread.c: Updated to handle N_CATCH symtab types.
6368 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6370 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6371 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6372 when printing the type.
6374 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6376 * valprint.c (val_print): Use `baseclass_addr' to access the
6377 baseclasses pointed to via the derived class object at VALADDR.
6379 * values.c (baseclass_addr): New function. Casts derived pointers
6380 to baseclass pointers taking virtual baseclasses and multiple
6381 inheritance into account.
6383 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6387 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6389 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6390 exp_valid_block field correctly.
6392 * infrun.c (wait_for_inferior): When checking "don't even think
6393 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6394 also check step_resume_breakpoint.
6395 Insert breakpoints and continue (not step) if
6396 step_resume_break_address != NULL, even if another_trap.
6397 If trap_expected and we enter sigtramp, then set up a
6399 If trap_expected is set when we hit the step_resume_break,
6401 When calling resume and trap_expected says tell resume to step
